Explicit Dynamic Analysis of Tensional & Torsional Propagations on Composite Material with Dog Bone Shaped Testing Specimen

Abstract

In general the composite are made by percentage of mixed or arrangement or concentration of material properties to increase the strength and advantages of the materials. Toeliminate the holding and gluing problems making the direct tensile strength test hard and torsional momentum loads to be applied, a new method of testing specimens prepared using 3d designing CATIA software to make the dog bone shape is assessed whether it could be applied to determine accurate direct tensile strength values and torsional loads over al alloy materials. In the project, i here considered 3 conditions, High percentage of aluminum alloy and low percentage of the silicon, Low percentage of aluminum alloy and high percentage of the silicon and Balanced percentage of aluminum alloy and silicon A series of modeling and analysis was performed using finite element method (ansys workbench) to investigate the deformation and stress to change of effect by material properties. A proper mechanical material property of the specimens was suggested and ideal failure of the dog bone shaped specimens was determined according to the results obtained from this study.
