摘　　要：通过对复合材料加筋壁板的后屈曲有限元分析和试验,给出了复合材料加筋壁板的临界载荷、损伤演化和后屈曲承载能力。理论预测与试验结果符合情况良好。FE analysis of postbuckling behavior and experiments of stiffened composite panels were conducted to give critical loads, damage evolution and load carrying capabilities of stiffened composite panels. The results indicate good agreement between predicted postbuckling load carrying capabilities of the stiffened composite panels and experimental data.
