Abstract
Sheet metals forming have been widely used in various app lications such as in automotive,aerospace and manufacturing industries either through cold or hot work to deform it.This depends on its mechanical properties and desirable stress-strain behaviour of sheet metals when subjecting to deforming load.The main purpose of this project is to design a special method to determine the shear strength of sheet metals by conducting a shear test.There are many types of shear tests had been done to determine the shear yield strength and plastic deformation of the selected sheet metal.It can be done by using Marciniak in-plane torsion test,Miyauchi shear test and also based on ASTM B831-14 method.Hence in this study,a group of shear test specimen was prepared as well as a special fixture was designed and fabricated to grip the shear test specimen during the test.The shear test specimens were fabricated from an automotive hood and door parts to determine its tensile and shear strengths by using a universal testing machine.The shear yield strength test results obtained from the developed method are approximately half of its tensile yield strength test results for the hood specimens but for the door specimens,the shear yield strength test results are quite high than the expected result.In addition,low percentage of difference of shear yield strength was obtained between the experimental results and theoretical results calculated by using the Tresca and von Mises Criterion for the hood specimens.Meanwhile,high percentage of difference of shear yield strength is obtained for the door specimens and this is greatly influenced by several factors.The analysis of the factors which influenced the shear test results is done for a future study.
