摘要： 应用提出的全程分析方法和三维逐渐累积损伤理论，对层合板的冲击过程以及冲击后含损伤层合板在拉伸载荷下的破坏过程进行详细分析。研究不同冲击能量、不同材料的冲头、不同复合材料体系和不同铺层方式等因素对层合板冲击损伤及剩余抗拉强度的影响规律，为更有效地进行复合材料抗冲击结构设计提供一定的指导作用。

Abstract: The impact damage process and residual tensile strength after impact of laminated composites are analyzed by the whole-process analysis method and 3D progressive damage theory. The influence of impact energy, impact tup, composite materials, and ply orientation angles on the impact damage and residual tensile strength of laminated composites are researched, which provides the guidance for the structure design resisted impact of laminated composites.

Key words: Composite laminates, Impact, Influence factors, Residual tensile strength
