中文摘要：

提出了一种基于不同铺层缺口边应力解析计算模型的含缺口层压板剩余强度研究方法。以含缺口层压板0°°°层缺口边平均应力与无缺口层压板纵向拉伸强度的比值为失效表征参数，对拉伸载荷作用下含缺口层压板剩余强度进行研究。全面分析了缺口边应力分布，计算获得了T300／1034-C层压板0°层的平均应力随缺口边距和缺口半径的变化趋势，比较了四种工程常用复合材料板0°层平均应力的变化趋势。不同铺层层合板开口后的剩余强度与现有试验结果比较，验证了建立的分析方法的可行性。

英文摘要：

A method to predict the residual strength of composite laminates with notch is presented based on the analytical solved model of the notch-edge stress. Using the 0° layer average stress ratio of the laminate with notch to the one without notch as failure characterization parameter, the residual strengths are studied comparatively. As re- suits are： trend which the failure characterization parameters change with the notch distance and aperture of 90° and 0°°layer is calculated, the residual strengths are also obtained, for T300/1034-C laminate plate. Change trends of the failure characterization parameters are compared, for four kinds of common engineering laminate plate. The ana- lytical results are compared with the experimental ones, which certified the validity of the developed method.
