A physically-based continuum damage mechanics model for numerical prediction of damage growth in laminated composite plates
Creators: name: Williams, Kevin V.
Publisher: name: University of British Columbia
Year: 2009

description: Rapid growth in use of composite materials in structural applications drives the need for a more detailed understanding of damage tolerant and damage resistant design. Current analytical techniques provide sufficient understanding and predictive capabilities for application in preliminary design, but current numerical models applicable to composites are few and far between and their development into well tested, rigorous material models is currently one of the most challenging fields in composite materials. The present work focuses on the development, implementation, and verification of a plane-stress continuum damage mechanics based model for composite materials. A physical treatment of damage growth based on the extensive body of experimental literature on the subject is combined with the mathematical rigour of a continuum damage mechanics description to form the foundation of the model. The model has been implemented in the LS-DYNA3D commercial finite element hydrocode and the results of the application of the model are shown to be physically meaningful and accurate. Furthermore it is demonstrated that the material characterization parameters can be extracted from the results of standard test methodologies for which a large body of published data already exists for many materials. Two case studies are undertaken to verify the model by comparison with measured experimental data. The first series of analyses demonstrate the ability of the model to predict the extent and growth of damage in T800/3900-2 carbon fibre reinforced polymer (CFRP) plates subjected to normal impacts over a range of impact energy levels. The predicted force-time and force-displacement response of the panels compare well with experimental measurements. The damage growth and stiffness reduction properties of the T800/3900-2 CFRP are derived using published data from a variety of sources without the need for parametric studies. To further demonstrate the physical nature of the model, a IM6/937 CFRP with a more brittle matrix system than 3900-2 is also analysed. Results of analyses performed under the same impact conditions do not compare as well quantitatively with measurements but the results are still promising and qualitative differences between the T800/3900-2 and IM6/937 are accurately captured. Finally, to further demonstrate the capability of the model, the response of a notched CFRP plate under quasi-static tensile loading is simulated and compared to experimental measurements. Of particular significance is the fact that the experimental test modelled in this case is uniquely suited to the characterization of the strain softening phenomenon observed in FRP laminates. Results of this virtual experiment compare very favourably with the measured damage growth and force-displacement curves.

description: We show that the polygamous nature of multi-party quantum correlations can be characterized in a {\em stronger} form based on Tsallis $q$-entropy and $q$-expectation value. By considering the amount of entanglement that can be distributed in multi-party systems, we establish a class of strong polygamy inequalities of multi-party entanglement in terms of Tsallis $q$-entropy and $q$-expectation for $q \geq 1$. Our new class of inequalities is in fact tighter than the usual polygamy inequalities of multi-party entanglement, and the tightness is explicitly illustrated by an example. Moreover, our new class of inequalities is concerned with the $q$-expected entanglement distributed between a single party and any possible subsets of the rest parties whereas the usual polygamy inequality only considers the entanglement between a single party and another. We further establish the equivalence between strong polygamy inequalities of quantum entanglement and quantum discord distributed in multi-party quantum systems.

Subjects: Obese adolescents

description: Research shows that the association between depression and obesity may be strongest among the most obese individuals. Appearance is a central evaluative dimension for females in Western culture, therefore body dissatisfaction can contribute directly to depression. Adolescents and females are at greater risk for self-esteem problems because body image is an important component of their self-esteem. The present study will add to the existing literature on adolescent obesity by examining the associations between family functioning, self-esteem levels, and depression in a self-selected sample of female adolescents who attended a weight-loss program. More specifically, this study will investigate how high and low levels of self-esteem and family functioning affect depression levels. Reasons for such an investigation are to increase the awareness of the effects and causes of depression levels among obese children and adolescents. A total of 45 obese adolescents with a mean age of 13.32 years participated in the initial evaluations (baseline measures). Fifty-three percent of the participants were Caucasian, 22% were Hispanic, 20% were African American, and 4% were multi-racial. The mean BMI was 34.04 kg, and ranged from 25.80 to 56.17. A multiple regression analysis was conducted to determine a relationship between body image and depressive symptoms and between self-esteem and depressive symptoms. The analysis produced a significant relationship between self-esteem and depressive symptoms, t(39) = -7.20, p .001 and between body image and depressive symptoms, t(39) = 2.52, p < .02. The overall model was also significant F (2,39) = 47.16, p < .001 in accounting for 71% of the total variance. These results indicate that as predicted, when there is an increase in self-esteem levels, there is a decrease in depressive symptoms. There was also a positive relationship between body image level and severity of depressive symptoms. In order to further examine the relationship between family functioning and level of depressive symptoms, a multiple regression was conducted, which included five subscales of the SFI. No significant relationship was found between family functioning and depressive symptoms

description: Discontinuous Galerkin (DG) methods provide a means to obtain high-order accurate solutions in regions of smooth fluid flow while, with the aid of limiters, still resolving strong shocks. These and other properties make DG methods attractive for solving problems involving hydrodynamics; e.g., the core-collapse supernova problem. With that in mind we are developing a DG solver for the general relativistic, ideal hydrodynamics equations under a 3+1 decomposition of spacetime, assuming a conformally-flat approximation to general relativity. With the aid of limiters we verify the accuracy and robustness of our code with several difficult test-problems: a special relativistic Kelvin--Helmholtz instability problem, a two-dimensional special relativistic Riemann problem, and a one- and two-dimensional general relativistic standing accretion shock (SAS) problem. We find good agreement with published results, where available. We also establish sufficient resolution for the 1D SAS problem and find encouraging results regarding the standing accretion shock instability (SASI) in 2D.

description: This report includes an analysis of traffic accident data in Kentucky tor the years of 1988-1992. A primary objective of this study was to determine average accident statistics tor Kentucky highways. Average and critical numbers and rates at accidents were calculated for various types of highways in rural and urban areas. These data can be used in Kentucky's procedure to identify locations that have abnormal rates or numbers of accidents.  Another objective of this study was to provide data which can be used in the preparation of the problem identification portion of Kentucky's Annual Highway Safety Plan. County and city accident statistics were analyzed. A summary of results and recommendations in several problem identification areas is presented. These general areas include alcohol, occupant protection, speed, pedestrians, bicycles, motorcycles, and vehicle defects. Other areas included in the analysis included drugs, school bus accidents, and truck accidents.

description: We investigate theoretically the combined effects of the electron-electron and the Rashba spin-orbit interactions on two electrons confined in quasi-one-dimensional AlInSb-based double quantum dots. We calculate the two-electron wave functions and explore the interplay between these two interactions on the energy levels and the spin of the states. The energy spectrum as a function of an applied magnetic field shows crossings and anticrossings between triplet and singlet states, associated with level mixing induced by the spin-orbit coupling. We find that the fields at which these crossings occur can be naturally controlled by the interdot barrier width, which controls the exchange integral in the structure.

Spectral signature of atmospheric winds in high resolution transit observations

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: The study of exoplanet atmospheres showed large diversity compared to the planets in our solar system. Especially Jupiter type exoplanets orbiting their host star in close orbits, the so-called hot and ultra-hot Jupiters, have been studied in detail due to their enhanced atmospheric signature. Due to their tidally locked status, the temperature difference between the day- and nightside triggers atmospheric winds which can lead to various fingerprints in the observations. Spatially resolved absorption lines during transit such as sodium (Na) could be a good tracer for such winds. Different works resolved the Na$^-$ absorption lines on different exoplanets which show different line widths. Assuming that this could be attributed to such zonal jet streams, this work models the effect of such winds on synthetic absorption lines. For this, transiting Jupiter type planets with rotational velocities similar to hot and ultra-hot Jupiter are considered. The investigation shows that high wind velocities could reproduce the broadening of Na-line profiles inferred in different high-resolution transit observations. There is a tendency that the broadening values decrease for planets with lower equilibrium temperature. This could be explained by atmospheric drag induced by the ionization of alkali lines which slow down the zonal jet streams, favoring their existence on hot Jupiter rather than ultra-hot Jupiter.

Our mere and foremost objective of such network infrastructure is to develop dependency of communication and institution intelligence. each mobile node is related to transmitter and receiver for wireless communication and knowledge exchange, small processor for computation purpose and process, flush memory for storage at the side of battery to produce energy to all or any connected devices. It uses connecting board to mound all such necessary elements along. the entire phenomena build them self-configurable nodes to deploy into any scenario any surroundings. they will be deployed into hostile and resistance surroundings for temporary purpose. thanks to a distinct nature of such network, it should become crucial a part of performance of actual system like military or emergency services. Security has become a primary concern so as to produce protected communication between mobile nodes during a hostile surroundings. not like the wire line networks, the distinctive characteristics of mobile unintended networks create variety of nontrivial Challenges to security style, like open peer-to-peer spec, shared wireless medium, demanding resource constraints, and extremely dynamic topology. Mobile nodes could deploy into discretionary topology with none coming up with and random choice. Here, destination is also deployed for means from supply and might be out of vary from supply node. Routing protocol is employed to see route among mobile nodes. Consequently, a load balancer may be a mechanism or device provides distribution and traffic handling facility with dependability. It improves the performance by nearly implements the logic of distribution. They improve the performance of applications by decreasing the burden on servers related to managing and maintaining application and network sessions, likewise as by playacting application-specific tasks. Project works think about Energy Aware Load leveling Multipath Routing (EALBM) because the base work and explore some prospects of improvement.

Using suitable approximations to extract physics from quantum space-times we establish that: i)future null infinity of the quantum space-time is sufficiently long for the the past vacuum to evolve to a pure state in the future; ii) this state has a finite norm in the future Fock space; and iii) all the information comes out at future infinity; there are no remnants.

Publisher: name: Zenodo
Year: 2024

description: Since the dawn of time, the callous and inhuman tradition of discriminating against the third gender hasbeen prevalent in almost every society and every part of the world, thus plunging these poor souls into avast ocean of unspeakable agony and miseries. Inspite of many sensitive authors, poets and activistsstriving to raise their voice for them, this queer community's predicament remains pretty much the same,courtesy a disheartening lack of probing and insightful literature delineating their horrifying woes. Thepresent paper is a small attempt to highlight the predicament of the third gender by studying, analysing anddiving deep into their tormenting grievances. This paper also aims to employ the queer lens in order tofathom as well as provide a probing insight into the hijra community's genuinely unsettling dilemmaregarding their social standing. Finally, this paper outlines the origin of the queer theory, while alsopresenting a comparative analysis of the queer in the Indian context. And then, using its explained queertheoretical approach, this paper studies the woeful narrative of Laxminarayan Tripathi, thus highlightingthe plight of the third gender and giving a screeching wake up call to a sleeping society to act before it'stoo late.

description: Runaway OB stars are ejected from their parent clusters via two mechanisms, both involving multiple stars: the dynamical ejection scenario (DES) and the binary supernova scenario (BSS). We constrain the relative contributions from these two ejection mechanisms in the Small Magellanic Cloud (SMC) using data for 304 field OB stars from the spatially complete, Runaways and Isolated O-Type Star Spectroscopic Survey of the SMC (RIOTS4). We obtain stellar masses and projected rotational velocities $v_r\sin i $ for the sample using RIOTS4 spectra, and use transverse velocities $v_{\rm loc}$ from $\it{Gaia}$ DR2 proper motions. Kinematic analyses of the masses, $v_r\sin i $, non-compact binaries, high-mass X-ray binaries, and Oe/Be stars largely support predictions for the statistical properties of the DES and BSS populations. We find that dynamical ejections dominate over supernova ejections by a factor of $\sim 2-3$ in the SMC, and our results suggest a high frequency of DES runaways and binary ejections. Objects seen as BSS runaways also include two-step ejections of binaries that are reaccelerated by SN kicks. We find that two-step runaways likely dominate the BSS runaway population. Our results further imply that any contribution from $\it{in-situ}$ field OB star formation is small. Finally, our data strongly support the post-mass-transfer model for the origin of classical Oe/Be stars, providing a simple explanation for the bimodality in the $v_r\sin i $ distribution and high, near-critical, Oe/Be rotation velocities. The close correspondence of Oe/Be stars with BSS predictions implies that the emission-line disks are long-lived.

description: Salinity intrusion in a river may have an adverse effect on the quality of life and can be perceived as a modern-day curse. Therefore, it is important to find technical ways to monitor and forecast salinity intrusion. In this paper, we designed a forecasting model using Simple Exponential Smoothing method (SES) which performs weekly salinity intrusion forecast in Ham Luong river (HLR), Ben Tre province based on historical data obtained from the Center for Hydro-meteorological forecasting of Ben Tre province. The results showed that the SES method provides an adequate predictive model for forecast of salinity intrusion in An Thuan, Son Doc, and Phu Khanh. However, the SES in My Hoa, An Hiep, and Vam Mon could be improved upon by another forecasting technique. This study suggests that the SES model is an easy-to-use modeling tool for water resource managers to obtain a quick preliminary assessment of salinity intrusion.

description: To determine the soil infiltration characteristics of pine and acacia plantations, we used a double-ring infiltrometer in 15 different locations of up-hill, mid-hill and down-hill part in each kind of plantation from June to August, 2018. The spatial infiltration characteristics of the soil at three plots (with no tree, with acacia tree and with pine tree) was determined by dye tracer method. The factors having an impact to the infiltration process were also analyzed. The main findings include: (1) The soil infiltration rate under both pine and acacia plantation decreased over time and it was the highest in the bottom of the hill and the lowest in the middle of the hill. The infiltration rate and the total infiltrated water in one hour at the acacia plantation were higher than ones at the pine plantation. However, statistical significant difference was only found for stable infiltration rate between two plantations; (2) The area and the depth of infiltrated water were the highest at the plot without trees, smaller at the soil of acacia plot and smallest at the soil of pine plot. All spatial infiltration rates were within the findings of previous studies; (3) The result indicated that soil with high ground cover has high infiltration rate. Để xác định đặc điểm thấm nước của đất dưới rừng trồng Thông và Keo, vòng đôi đo tốc độ thấm đã được sử dụng để đo ở sườn trên, sườn giữa và sườn dưới (5 lần/ ví trí) cho mỗi loại hình rừng từ tháng 6-8/2018. Trong khi, thuốc nhuộm được sử dụng để kiểm tra đặc điểm thấm nước của đất theo không gian trên 3 ô (ô không có cây, ô trồng Keo và ô trồng Thông). Các yếu tố ảnh hưởng đến đặc điểm thấm nước cũng được phân tích. Kết quả chính thu được: (1) Tốc độ thấm ở cả hai loại rừng giảm dần theo thời gian và cao nhất ở sườn dưới, nhỏ nhất ở sườn giữa. Cả tốc độ thấm và tổng lượng nước thấm trong một giờ của rừng keo đều cao hơn so với rừng Thông. Tuy nhiên, chỉ có tốc độ thấm ổn định là khác biệt có ý nghĩa thống kê; (2) Diện tích và độ sâu nước thấm xuống đất cao nhất ở ô không có cây, nhỏ hơn ở ô trồng Keo và nhỏ nhất ở ô trồng Thông; (3) Độ che phủ thực vật càng cao thì lượng nước thấm càng lớn.

description: We study SU(2) Yang-Mills quantum mechanics with N=2,4,8 and 16 supercharges. This describes the non-relativistic dynamics of a pair of D0-branes moving in d=3,4,6 and 10 spacetime dimensions respectively. We show that as the D0-branes orbit, states undergo a Berry holonomy described by the four Hopf maps. For the N=2 theory, the associated Hopf map is the Mobius bundle and its effect is to turn the D0-branes into anyons with exchange statistics +i and -i. For the N=4,8 and 16 theories, the Hopf maps give rise to Berry connections that are familiar to physicists: the U(1) Dirac monopole; the SU(2) Yang monopole; and the SO(8) octonionic monopole.

description: Southeast Asian countries and Vietnam in particular are facing water security challenges; water reclamation is increasingly being considered as a favorable solution. Despite the availability of suitable technologies, several constraints often prevent stakeholders and especially decision makers exploiting their potential. In this paper we present the results of applying a decision support tool (DST) to evaluate water reclamation, support pre-feasibility studies and build capacity for water reclamation in Vietnam. The DST and its data are open access, providing information related to local and international water and wastewater quality standards. In this research we identified high potential Vietnamese case studies and conducted a systematic PISTLE analysis considering six dimensions (Political, Institutional, Social, Technical, Legal and Economic) at a multiple local stakeholder workshop. Key barriers and drivers for water reclamation implementation were identified. Measures proposed during the workshop could serve as a starting point for the development of water reclamation projects in Vietnam.

description: We report an investigation of dispersion management of an all-polarization maintaining Er-fiber oscillator mode-locked via nonlinear amplification loop mirror in a figure-nine cavity configuration with two output ports. The performance of the laser was investigated within the net cavity dispersion ranging from -0.034 ps2 to +0.006 ps2. We show that the spectral and temporal phase of the pulses at both figure-nine outputs have clearly different characteristics. One of the laser outputs provides pulses with significantly better quality; nonetheless, the rejection output also offers ultrashort pulses with broad spectra. Pulses as short as 79 fs with an energy of 83 pJ were generated directly from the laser in the near-zero dispersion regime.
Impacts of the Extended-Weight Coal Haul Road System

description: The Extended-Weight Coal Haul Road System, created by Kentucky's Legislature in 1986, consists of all roads which carry over 50,000 tons of coal in a calendar year. Trucks hauling coal on this system are authorized to exceed normal weight limits through the payment of an annual decal fee. A research study was initiated in July of 1992 to analyze the impacts of the extended-weight system. This interim report, prepared after one year of a three-year study, describes the analyses performed thus far and presents preliminary findings, recommendations, and a discussion of future work.  Analyses in this report are based on: historical data on coal production and transportation: data from coal decal applications; interviews of legislators, transportation official, coal company representatives, and coal trucking representatives: newspaper articles; vehicle classification data; a pavement cost analysis; and accident data.  Preliminary conclusions include: 1) The extended-weight system has apparently been somewhat successful in accomplishing its primary objectives: to enhance the competitiveness and economic viability of Kentucky's coal industry and to eliminate the perceived need for coal haulers to violate the law in order to be competitive; 2) Overall accident rates are no higher on the extended-weight system than on other comparable routes, but the fatal accident data is significantly higher on the extended- weight system; 3) The coal-decal fee structure results in a net annual loss in Road Fund revenue of approximately $2 trillion; 4) Forty percent of the revenue from data sales is allocated to the counties, although less than ten percent of the extended-weight system is county-maintained; 5) The heavier weights of coal-decal trucks add approximately $9 million annually to pavement overlay costs and increase other highway costs to an (as yet) undetermined extant; 6) Road users throughout the state are subsidizing the movement of Kentucky coal by underwriting the increased costs of maintaining and improving the infrastructure.  The following preliminary recommendations ware developed: 1) Route geometry and cross section should be considered when deciding which routes will be included in the extended-weight system; 2) The selection of routes for the extended-weight system should include consideration of system connectivity; 3) Countermeasures should be evaluated and implemented to alleviate the braking problem for heavy trucks approaching signalized intersections; 4) A revision to the allocation of Energy Recovery Road Fund dollars should be considered to more accurately reflect the composition of the extended-weight system.

Subjects: subject: Transportation Engineering

description: On September 30, 1993, the Condominium Council of Co-Owners of Fort Wright Trace in Fort Wright, Kentucky requested of the Director of the Kentucky Transportation Center that a member of his staff meet with them to review and visually inspect the drainage and pavement conditions in their community. The Head of the Pavements Section met with representatives of the Council on October 13, 1993 as a part of the Transportation Center's Technology Exchange Program.  A visual inspection was conducted of Cloverfield Lane and its associated parking areas beginning at the intersection of Cloverfield Lane and Castle Hill Lane and continuing to the end of Cloverfield Lane.  It should be noted that all statements, conclusions, and recommendations that follow in this report are based strictly upon the visual inspection. No field measurements were made, nor were any laboratory tests conducted.
Universal properties of the Kardar-Parisi-Zhang equation with quenched columnar disorders

description: Inspired by the recent results on totally asymmetric simple exclusion processes on a periodic lattice with short-ranged quenched hopping rates [A. Haldar, A. Basu, Phys Rev Research 2, 043073 (2020)], we study the universal scaling properties of the Kardar-Parisi-Zhang (KPZ) equation with short-ranged quenched columnar disorder in general d-dimensions. We show that there are generic propagating modes in the system that have their origin in the quenched disorder and make the system anisotropic. We argue that the presence of the propagating modes actually make the effects of the quenched disorder irrelevant, making the universal long wavelength scaling property belong to the well-known KPZ universality class. On the other hand, when these waves vanish in a special limit of the model, new universality class emerges with dimension d = 4 as the lower critical dimension, above which the system is speculated to admit a disorder-induced roughening transition to a perturbatively inaccessible rough phase.

Performance of the Crash Cushion Attenuating Terminal (CAT) in Traffic Accidents

Subjects: subject: Transportation Engineering

description: The objective of this study was to report the results of the continued monitoring of the performance of the Crash Cushion Attenuating Terminal (CAT) in traffic accidents.  The documented performance of the CAT system in traffic accidents justifies additional use. A recommended location would be at median piers and bridge abutments in narrow medians. While accidents involving this system should continue to be evaluated, this evaluation results in the conclusion that the CAT system could be classified as operational.  The performance of the CAT system indicates a couple of areas which should be addressed. For installations in a raised median, the raised median should be modified so that the back side of the system would be at the proper height. This modification has been designed with changes made at locations on the Western Kentucky Parkway. The amount of translation was not as great as expected. The design of the system should be evaluated to determine if modifications should be made to allow more translation to occur.
Weak measurement: Effect of the detector dynamics

description: A general approach to the measurement of an observable with pre- and post-selection is presented. The limit of weak measurement is studied in detail, and it is shown that the phase of the probe, including a Hamiltonian contribution to it, gives rise to observable effects, since the coherence of the probe is essential for the concept of complex weak value to be meaningful. As a particular example, the measurement of a spin component is considered. We find that the contribution of the imaginary part of the weak value is sizeable in this case.

Superfluid pairing between fermions with unequal masses

description: We consider a superfluid state in a two-component gas of fermionic atoms with equal densities and unequal masses in the BCS limit. We develop a perturbation theory along the lines proposed by Gorkov and Melik-Barkhudarov and find that for a large difference in the masses of heavy ($M$) and light ($m$) atoms one has to take into account both the second-order and third-order contributions. The result for the critical temperature and order parameter is then quite different from the prediction of the simple BCS approach. Moreover, the small parameter of the theory turns out to be $(p_{F}|a|)/\hbar)\sqrt{M/m}\ll1$, where $p_{F}$ is the Fermi momentum, and $a$ the scattering length. Thus, for a large mass ratio $M/m$ the conventional perturbation theory requires significantly smaller Fermi momenta (densities) or scattering lengths than in the case of $M\sim m$, where the small parameter is $(p_{F}|a|)/\hbar)\ll1$. We show that 3-body scattering resonances appearing at a large mass ratio due to the presence of 3-body bound Efimov states do not influence the result, which in this sense becomes universal.
