摘　　要：采用显式有限元软件ABAQUS/Explicit模拟纤维增强复合材料层合板的侵彻行为。重点分析弹头形状、纤维铺设方式、层数等因素对层合板抗弹性能的影响,给出了层合板在不同弹头冲击下的侵彻破坏特征和模态,获得了弹道极限速度。模拟结果与理论计算结果及已有实验结果进行了对比,吻合较好,这可为工程实际提供参考。The penetration behavior of a fiber reinforced composite laminated plate was simulated by using ABAQUS/Explicit finite element code. The influences of projectile geometries, fiber orientation and layer number on ballistic performance were analyzed. The damage characteristics and modes of the plate under impacting of projectiles with different geometries were obtained, and the ballistic limit velocity was gained. It was shown that the simulation results agree well with the test ones. The results provided a reference for engineering application.
