    S. K. Panthi1, Sanjeev Saxena2

    CMC-Computers, Materials & Continua, Vol.32, No.1, pp. 15-28, 2012, DOI:10.3970/cmc.2012.032.015

    Abstract 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… More >
