Investigating aluminum plate with different geometrical shape by using DIC tension test

Sammanfattning: This subject mainly uses Aluminum sheet metal material as the research object which is used in Volvo XC90 door, the elastic plasticity deformation within the different material angles and notch shape investigated with MTS tensile test equipment under uniaxial tension. The local strain curve studied by using DIC method to obtain the conventional physical quantity. Combining ABAQUS to analyze the distribution of stress in elastic and plastic regions, also use MATLAB to combine various parameters, and finally analyze the desired experimental results to find a relatively stable notch shape based on the yield curve and stress concentration factor.
