| 摘 要： | 本文采用一种包含材料硬化指数ｎ和速率敏感性指数ｍ的刚粘塑性有限元模型，阶段硬化处理考虑到等效应力公与应变率有关，依据线粘性材料假设，提出了考虑材料参数ｎ、ｍ影响的刚粘塑性有限元初始速度场自动生成方法，改进了文献［３］方法。数值模拟结果与有关文献的计算和实验结果进行了比较，表明本文方法是有效的。

| Abstract: | In this paper, the rigid- plastic FEM considering material hardening exponent n and the strain--rate sensitivity exponent m is adopted. The assumption of linear viscous material is introduced. The generation method of the initial velocity field considering material exponent n and m effects is developed. The comparison between Computed results and references' ones show that the method developed by the author is reasonable. |
