| Abstract: | The punching process of Q235A metal sheet in 4mm thickness has been simulated by use of explicit dynamic analysis FEA program LS-Dyna. The punching principle, maximum main stress, and the changing rule of punching force have been analyzed as per the FEA results. It is obtained that the theory meets the practice well, which provides reference for optimization of punching process parameter and developing of related products. |
