摘　　要：考虑层压结构受冲击后的“花生壳形”分层及分层损伤引起的局部不对称性和耦合效应 ,并考虑压缩加载过程中可能出现的多层分级屈曲 ,发展一种计算低能冲击层压板受压剩余强度计算方法。Under the consideration of laminate peanut-shape delamination caused by low-energy impact and local unsymmetry with the delamination as well as their coupling effect. A numerical analysis method is developed for calculating the residual compressive strength of laminates in low-energy impact, including considering effect of multiply classify yields of laminates. The numerical analysis show that the prediction agrees fairly well with the experimental results.
