摘要
在现有计算程序的基础上 ,引入有限变形几何框架及大变形条件下的Bodner Partom本构模型。同时 ,利用实验数据确定了材料的物理参数。计算与实验的对比说明 ,所给出的非线性几何计算及物理参数的确定方法可用于穿破甲过程。
The geometric frame of finite deformation and Bodner Partom constitutive equations have been introduced into the finite element analysis of hypervelocity impact in this paper. The material physical parameters are determined by comparison of the one dimensional calculations with the experimental results. The comparison of the calculations with the experiment of a tungsten alloy projectile impacting a semi infinite plate that the B P constitutive equations and the geometric non linearity introduced have can be used in hypervelocity impact calculations.
