摘　　要：对复合材料展状结构的低速冲击问题进行了分析。分析中采用作者提出的接触－冲击数值算法。这个算法可用于分析任意构形的冲击物对任意构形的复合材料层状结构低速冲击的响应．用该算法分析了层板的冲击响应，并预报分层损伤．预报的损伤与实验结果基本符合。FEM analysis for laminated composite structures subjected to low-velocity impact is performed in this paper.In the analysis,the contact-impact numerical algorithm developed by the authers is used, and the configurations of impacters and laminated structures can be taken into account.The analysis of impact responses and the prediction of impact damage have been carried out.Good agreement can be observed by the comparison of the experimental results with the numerical ones.
