Authors: Elamvazhudi B , Gopalakannan S 
Published: December 2020

Abstract
Incorporating nanofillers in epoxy resin is a novel approach to improve the mechanical properties of polymer composites. Recent studies discloses that the inclusion of nanofillers such as SiC, CNT, alumina and nanoclay into epoxies at micro and nanoscale levels enhances the mechanical properties of epoxies. In this research, the improved mechanical properties of nanoclay modified carbon/glass fibre-reinforced polymer nanocomposite (FRPNC) were investigated. The neat DGEBA epoxy resin was modified with nanoclay at different wt % (0.5- 2wt %) by ultrasonication process for achieving better dispersion of nanofillers. The modified polymer laminates were fabricated with unidirectional carbon/glass fibres with the stacking sequences of (0°G/0°G/0°C)S using hand lay-up process. The mechanical properties such as mode III delamination toughness, tensile strength and flexural strength were investigated using servo controlled hydraulic universal testing machine and 3-point bending test setup respectively. The highly cross linked structure between epoxy and nanoclay particles improves the mode III fracture toughness, tensile and flexural properties. The damage mechanisms of fractured specimens are characterised by SEM images.

Authors: Srinadhi K , Kannan B T 
Published: December 2020

Abstract
A Shock tube is a device often used to recreate the shock phenomena by several methods. The present work is a preliminary study to analyse the efficiency of baffles in suppressing the noise generated from the shock associated jet ejected from the duct exit. The experiment was performed at a shock Mach number of 1.27 using a diaphragm based, small scale, open ended shock tube. Parametric study conducted by varying the baffle dimensions such as outer diameter, hole diameter and porosity reveals that the baffles with hole diameter less than half of the baffle diameter and with a greater porosity is a cost effective and efficient noise suppressor for shock associated jets.

Published: December 2020

Abstract
A finite element analysis was conducted in this research to understand the distribution of temperatures along with the depth of the standard steel W40×235 beam. The considered thermal loads were those of open environments, including the radiation of the sun and the temperature of the air in addition to wind movement. The thermal analysis considered the total solar radiation, ground reflected radiation, longwave radiation, mutual surface radiation and heat convection as the thermal boundary loads. The analysis was carried out for the experimentally recorded conditions of a sunny summer day. The results showed that the vertical temperature gradient approaches zero with stabilized beam temperature after midnight and up to the sunrise. On the other hand, the vertical temperature gradients at the top and bottom surfaces continuously increase with time reaching their maximum values at approximately 2:00 PM. The maximum temperature gradients at the top and bottom surfaces of the beam were 10.2 and 9.1 °C for the conditions of the investigated day.

Authors: Gurusamy P , Ravi S , Mohanavel V 
Published: December 2020

Abstract
The study on the solidification of aluminium alloys has been reported by the squeeze casting method. In solidification analysis, the formation of casting plays a vital role. To provide quality casting, the preparation of composite is essential. Hence the liquid state processing of the squeeze casting technique is adopted. The application of pressure during the fabrication of composite would change the structure and properties of the developed composite. The squeezing pressure is assigned 30,60,90 and 110MPa, and the melting of the aluminium the selected temperature is 850°C, and the die temperature is 350°C respectively. At 30MPa, the solidification time is recorded at 69 seconds, and the pressure is increased to 110 MPa the solidification is recorded at 33 seconds. The cooling rate is reduced due to increasing squeeze pressure. K type thermocouple has been used to record the temperature values of the aluminium alloy. The theoretical solidification time is calculated, and the results are close to the values which have been taken from the experimental results. Further, the hardness value is identified to measure the grain structure formation in the aluminium alloy, which is correlated with the solidification process.

Authors: Raja N D , Prakash D S 
Published: December 2020

AbstractMaterials prepared using powder metallurgy route exhibit dimensional stability which is required to manufacture critical parts such as brake pads, inlet valves and nozzles. In this paper, composite materials consisting of 5 and 10 wt. % of Titanium-diboride reinforcement in AA6061 aluminium alloy was produced by the sintering process via green compaction. 2 wt. % of alumina was added as the secondary reinforcement to produce the hybrid composites. The produced composites and its hybrid were compared with the base material AA6061 to determine the changes in its density, wear and hardness. The green density and sintered density of the composites and its hybrids reduced by as much as 8.47 % compared to the respective theoretical density. Microscopic examinations showed that the addition of alumina with the Titanium-diboride reinforcement increased the wear resistance of the hybrid composites by 1.22 % compared to the base material. The hardness of the sintered composite increased with the addition of the two reinforcement materials. The hardness for the hybrid composite increased by 74.94 % compared to the base material. After wear test, the hardness of the base material reduced by 6.83 % but the hardness of hybrid composite having the highest composition of both reinforcement particles increased by 6.36 %. The study revealed that the sintering process and subsequent hardening of the composites and its hybrid enhance its hardness property compared to the base material. Interestingly, the wear which leads to the changes in its tribological properties increased the hardness property of the composite and its hybrid.

AbstractThe present study investigates the effect of Ce addition on the microstructure of Mg-6Al-1Zn alloy with the use of optical microscopy (OM), X-ray diffraction analysis (XRD) and scanning electron microscopy (SEM). The electrochemical corrosion behaviour of Mg-6Al-1Zn alloyed with different levels of cerium was investigated using static weight loss and polarization corrosion tests in 3.5% NaCl solution. The microstructural study reveals the grain refinement of the matrix and the stability of the phase β(Mg17Al12) were disintegrated into Al4Ce and distributed along the grain boundary. The literatures show that the intermetallic Al4Ce has a high melting point and expected to show better strength behaviour at relatively high temperatures. The electrochemical results show that cerium addition above 1.5wt.% increase the corrosion current density of the developed alloy which resulted in increasing corrosion rate. The best results of refined microstructure and corrosion resistance were obtained with 1.5wt.% cerium addition.

Authors: Singh N , Amendola A , Santos F , Benzoni G , Fraternali F 
Published: December 2020

Abstract
To optimize the seismic performance prescribed by modern structural codes, buildings and infrastructures must provide adequate safety for design level earthquake excitations, with limited levels of damage. This paper deals with the computational modelling of a bracing system with tensegrity architecture, which operates as a lightweight mechanical amplifier of longitudinal displacements in the transverse direction, efficiently limiting the interstory drifts while dissipating energy. The proposed brace is based on a D-bar tensegrity structure with a rhomboidal shape comprising Shape-Memory Alloy (SMA) tendons. The SMA tendons can develop austenitic-martensitic (solid to solid) transformations, which enable them to amplify the signals into wide super elastic hysteresis, while subjected to mechanical cycles, comprising strains up to 6÷8%, with no residual deformations. The enhanced energy dissipation of the proposed SMA-D-bar (SMAD) braces are demonstrated through computational simulations of the response of braced frame to real earthquake events. The efficiency of the intended bracing to minimize the seismic impact of the served structure lays the foundation for the development of novel seismic energy dissipation systems integrating principles of tensegrity with superelasticity.

Published: December 2020

Abstract
Seismic rehabilitation using Carbon Fiber Reinforcement Polymer CFRP is more often used worldwide. CFRP jacketing is the most common layout for columns and walls, however installing the CFRP sheet as diagonal ties increase shear capacity to walls instead of jacketing procedures, besides less CFRP materials is used reducing the cost to the retrofit work. It is know that CFRP sheets can be debonded from the concrete or masonry surface causing that the sheets will not develop its tensile capacity. Then CFRP anchors are introduced. It is presented the behavior of CFRP sheets as diagonal ties working even though sliding and CFRP anchors which attach the diagonal ties to concrete base and top of the masonry wall. The diagonal ties work at full tensile capacity even though the debonding and buckling presented under compression forces. CFRP anchors also provided a resistance capacity against sliding.
