| 摘 要： | 针对不同材料弹体由于其密度不同而导致其侵彻过程中三向应力分布上出现不同的问题，为了研究侵彻弹体的弹体材料对其在侵彻过程中三向应力的影响，文中采用刚性弹的侵彻模型再结合弹性力学知识，充分考虑装填物的泊松效应．针对具有一定外形和装药尺寸的侵彻战斗部弹体在侵彻过程中的三向应力进行了理论分析。得出了弹体最大三向应力随其密度的变化关系。

| Abstract: | Different material shell body conduced to different distributing of three-dimensional stress in shell body during penetrating because of its different density. To investigate influence of shell body material on three-dimensional in penetration body during penetrating, with adopting penetration model of rigidity projectile recombining to elasticity and Pois- son effect of fill, theory analysis are conducted in the present to investigate three-dimension stress of penetration warhead body with specified figure and charge measure during penetrating. The variation relationship of maximum three-dimension stress in body therewith its density is obtained. |

| Keywords: | penetration hard structure warhead three-dimension stress body density Poisson effect |
