AU - Saxena, Sanjeev TI - Prediction of Crack Location in Deep Drawing Processes Using Finite Element Simulation T2 - Computers, Materials \& Continua PY - 2012 VL - 32 IS - 1 SN - 1546-2226 AB - Sheet metal forming process like deep drawing subjected to large irreversible deformation. It leads to high strain localization zones and then internal or superficial micro defects. The deformation behavior and crack initiation in cylindrical deep drawing of aluminum alloy are simulated by the elasto-plastic finite element simulation. A1100-O and A2024-T4 sheet material are used in the simulation. Material properties based on the tensile and plane strain test is used in the simulation. Six cases are simulated in this study with different blank diameter. The simulated results are compared with the experimental results in terms of the crack location and critical punch displacement. The comparison of simulated results with experimental results shows a good agreement. KW - Fracture KW - deep drawing process KW - finite element simulation DO - 10.3970/cmc.2012.032.015
