Hypothesizing that the stress distributions don＇t refer to stressstrain history of explosive in pressing process ,the stress in the condition of steady load for charge of projectile body is analyzed and calculated by two methods: one is that the whole projectile body is divided into smaller lattices to solve ,the other one is that the whole projectile body is divided into smaller lattices firstly, and then local lattices are bridged according to the need for solving.

假设药柱的应力分布不涉及压制过程炸药的应力一应变历史，采用两种方法对装药弹体在静载荷下的应力进行分析计算，一种是将整个弹体划分成较小的网格进行求解，另一种是先对整个弹体进行网格划分，然后根据求解的需要对局部网格进行加密。
