Failure Test and Post-buckling Analysis of Composite Stiffened Panels Under Shear Load

  • 摘要: 针对复合材料加筋壁板在剪切载荷下的稳定性和承载特性,开展了破坏试验和后屈曲分析方法的研究。基于三维Hashin准则和平方应力准则作为复合材料层板和界面胶层的失效判据及刚度退化策略,建立了考虑渐进损伤的剪切破坏分析模型,利用编制的用户自定义UMAT子程序,实现了在ABAQUS中的应用和承载能力的求解。与试验结果相比,结构承载能力和应变状态数值分析与试验值吻合良好,预测的破坏模式也与试验结果一致,屈曲载荷和承载能力相对误差分别为5.4%和3.5%,验证了该建模分析方法的有效性。
