摘　　要：采用有限元法计算了某破甲弹发射时其内部炸药的应力应变分布，计算时选择了更为合理的计算模型以模拟弹壁与炸药间的相互作用。并绘制了炸药应力应变等值线，对炸药安全性估计和弹丸设计有一定参考价值。in this paper,the stress and strain distributions of the explosives inside a HEAT under firing conditions are calculated by rneans of FEM,using a more reasonalbe model to simulate the interaction between the explosives and the projectile wall.The stress and strain contours of the explosives are drawn.It is valuable to the estimation of explosive safety and the design of projectile.

关 键 词：破甲弹 应力分布 炸药安全性
