Analysis and Characterization of Tensile Property of Mg MMC using ANSYS
Abstract: The objective of the this research paper is to predict the stress and strain values of magnesium metal matrix composites using finite element analysis (FEA) and compare with the universal testing machine (UTM) results through the tensile load. The composites were prepared by semi solid stir casting process. Tensile specimens with ASTM B557 standard dimensions were prepared from the composites. These specimens were subjected to uni-axial tension under the 10 …

A Review: Effect of Different Shielding Gas on Weld Penetration in Stainless Steel in GTAW Process
Abstract: Gas tungsten arc welding (GTAW) is high quality and high precision welding process which is suitable for welding thin metals. Inert gases as helium and argon, carbon dioxide and nitrogen are used as a shielding gas to prevent the weld bead from air, dust and other contaminations in welding. There are so many welding process parameters which affect the weld quality in GTAW. Important process parameters which mainly affect the …

Static and Dynamic Balancing of Rotating Machineries in The Field: A Review
Abstract: Static and dynamic balancing of a rotor plays an important role in deciding the life of any turbo-machinery. Vibrations generated due to unbalance rotor is considered as one of the major factors that can lead to accelerating degradation of machine components or evencatastrophic failure, especially at high speed where reliability is important consideration. Rotor unbalance may result due to error in manufacturing process, wear and tear of rotating component, thermal …
