Dynamic Fracture of Ductile Metals at High Strain Rate
Authors: Pang Wei Wei , Zhang Guang Cai , Xu Ai Guo , Zhang Ping
Published: September 2013

Dynamic fracture of ductile metals at different strain rates and temperatures is studied via molecular dynamic simulations. The results show that both increase of temperature and decrease of strain rate reduce the yield strength, but the stress-strain curves separate prior to yield point at different temperatures. Both increase of temperature and strain rate shorten the duration of the stage of dislocation nucleation and slip. The stress-strain curves for various materials indicate that void nucleation needs not only lower yield strength but also lower fault energy. After the yield point, initially some defect clusters form along the loading direction. With the increasing of strain, small dislocation loops nucleate from some larger defect clusters, then quickly multiply and move on slip plane. When the stress exceeds a critical value, some voids nucleate in dislocation aggregation regions. The incipient void shapes are clavate and void distributions predominantly are along the perpendicular directions of tensile loading. Nucleated voids gradually grow into spherical-like shapes via emitting dislocations.

Authors: Zhao Qiu Yu , Li Xiao Yu
Published: September 2013

In this paper we provide a high-capacity information delay scheme based on eantangled states and quantum teleportation technology. By sharing EPR (Einstain-Rosen-Podolsky) pairs, one person can give the other person some information which cannot be read until he or she lets the latter do. By virtue of quantum teleportation technology, no one can gain more information about the key than guessing the key at random. So the scheme can gain high security. The fundamental principles of quantum physics guarantee its unconditional security. When the one decides to let the other get the information, he or she need only to send some dictates through a public classical channel. So the scheme is easier to carry out and more robust in practice.

Published: September 2013

Fourier transform (FT) infrared (IR) and Raman spectra of powders in the Biqi capsule, a commercially available national-level combination medicine, are measured to check the information on the most important active ingredient strychnine, which is in fact a highly toxic drug. Referring to the published FTIR absorption and FT Raman spectral data, from our ones we have found that the active ingredient - strychnine in our purchased Biqi capsule really exists and its net content is really not so high and therefore may not cause a serious harm to patients if an approved dosage is eaten. From this study one can see that the IR spectroscopic method is more suitable for this kind of drug identification than the Raman one using the Raman spectroscope in this experiment because strong fluorescent signals excited by lasers on the pharmaceutical excipients and other subordinate active ingredients generally cover up the fingerprint signals of the active ingredient in the drug.

The results indicate that the egg-shell type of catalyst is suitable for fast combustion and it can improve the efficiency of utilizing catalyst especially for noble metal catalyst. For situations where the active section of the catalyst is prone to be poisoned or where the lost of catalyst weight will happen, the egg-white or egg-yolk type is recommended for the reason that it can protect the catalyst from deactivation and the decrease of combustion efficiency is not significant. In additional, the model and the method presented can support the design and choose of the catalyst for different fuels.

The results show that the particles of two kinds of styrene-acrylate micro emulsion are regular sphericity in shape; The apparent viscosity of the coating decreases with the increase of the shear rate, indicating a pseudo-plastic flow characteristic. There is no obvious difference on the viscosity between the two coating under the condition of high shear rate. Compared with the coating prepared by non-crosslinked styrene-acrylate micro emulsion, the coating prepared by cross-linked styrene-acrylate micro emulsion has a bigger viscosity and a better property of water retention.

The corrosion failure analysis of an SA210 steel used in high pressure evaporator tube is conducted by XRD, SEM, OM. The result shows that the corrosion products in the inner wall of the steel tube is Fe3O4, mainly caused by the residual water in the evaporator tube corroding its inner wall with oxygen after the hydrostatic test of the boiler, finally leading to the corrosion leak of the tube.

Published: September 2013

The composite of carbon fiber reinforced polyethylene resin was prepared by using a twin-screw extruder. The effect of carbon fiber oxidation treating on the mechanical properties of carbon fiber reinforced polyethylene resin composite was researched. The tensile fracture failure mechanism of composite was analyzed for both untreated and air oxidation treated specimen. The experimental results indicate that when carbon fiber content is equal, the tensile strength and the elastic modulus of air oxidation-treated carbon fiber-reinforced polyethylene composite are improved than that of the untreated. When the fraction of adding carbon fiber is 3.99%, compared with the pure polyethylene resin matrix, the tensile strength, elastic modulus is increased by 13.12% and 172.91%, respectively. Compared to the untreated carbon fiber reinforced polyethylene resin composite, the tensile strength and tensile modulus is increased by 4.71% and 13.14%, respectively.

Accurate calculation of rock mechanics parameters is of great significance in developing comprehensive drilling and oil/gas development programme and technical measures, as well as reducing operation risk. It greatly relates to the reliability of ground stress field numerical calculation. This paper proposes a new method for calculation of 3D rock mechanics parameters, on the basis of acoustic logging data and lab core test data and also by reference to seismic velocity field. Taking Keshen 2 area in Tarim Basin as example, we have calculated 3D rock mechanics parameters using VB.NET calculation program, and drafted 3D rock mechanics parameters cloud charts of some profiles, showing small discrepancy against the acounstic logging interpretation data of production well. These 3D rock mechanics parameters calculated in this method can be directly applied for numerical calculation of ground stress field, providing references for fracturing parameter design and improving the simulation of reservoir stress field.

When TBM tunneling, the disc cutter directly in contact with the rock. The disc cutter is an important component of the TBM, so the numerical simulation study of disc cutter breaking rock process is established. The study contents disc cutter exerted vertical force on the rock. This is instructive for improving the disc cutter layout and improving the rock breaking capacity and tunneling efficiency. According to the rock Drucker-Prager plastic yield criterion lines and rock mechanical properties, finite element model of rock breaking by disc cutter was established by ANSYSWORKBENCH software and process of rock cutting with disc cutter was simulated. The rock elastic-plastic deformation occurred in the disc cutter effect, caused accumulation of rock damage, when the rock breaks completely damaged, get the vertical force exerted on the disc cutter, which is significance for the disc cutter layout and the calculation of force of TBM cutter breaking rock.

Current trends in precision machinery include increased adaptability, speed and reliability. This, combined with the development of artificially-intelligent automatic sensors can lead to the establishment of highly-reliable and systematic manufacturing systems. During the automation process, equipment process parameters frequently need to be adjusted to match the requirements of different processes. Thus how to best maintain normal equipment operation and stable quality through these frequent adjustments is a key issue for manufacturers. Therefore, high-quality automated production systems allowing for fast-changeover and real-time automatic detection and performance monitoring are effectively needed.
