火药的粘聚力对雷管壳体塑性失稳的影响

The Numerical Value Imitate and Studies of Plasticity and Unsteadiness Detonator Shell

文中采用有限元结构分析软件包ANSYS,对某型雷管的压药进程中壳体的弹塑性大变形力学行为、塑性失稳现象的研究方法进行了数值仿真计算。分析了工程中火药的粘聚力对雷管壳“挤鼓”的塑性失稳现象的影响,引出了有益的体验和结论。

This paper uses FEM software package ANSYS to numerical imitate the elastic and plastic deform and plasticity unsteadiness phenomenon of detonator in pressure. It analyses the cohension effect on plasticity unsteadiness phenomenon of detonator shell which is called 'crush knob' in the project. The beneficial experience and conclusion are drawn.
