摘　　要：探究了"波平轧制"工艺制备的钛/钢复合波纹板在弹道冲击载荷下界面的失效机理,分别建立含波纹界面与平面界面的钛/钢复合板有限元模型,采用基于双线性牵引分离准则下的内聚力单元模拟复合界面,对比分析子弹侵彻2种板材后的速度及破坏界面的形态。结果表明:在同样的弹道冲击条件下,波纹复合板对子弹动能的吸收效果强于平面复合板,平面板界面的破坏比波纹板界面更严重、更不稳定,复合波纹板完整性较好。The failure mechanism of the interface of the titanium/steel composite corrugated board prepared by the rolling process under ballistic impact load is explored,a finite element models of the titanium/steel composite boards with a corrugated interface and a planar interface is established separately,the composite interface is simulated by cohesive element based on bilinear traction separation criterion,the speed of the bullet after penetrating the two boards and the shape of the damage interfaces of the boards are compared and analyzed.The results show that under the same ballistic impact conditions,the corrugated composite board has a stronger absorption effect on the kinetic energy of the bullet than the planar composite board,and the damage of the planar board interface is more serious and unstable than the corrugated board interface.
