中文摘要
    为表征复合材料雷击烧蚀损伤,基于唯象分析方法,建立了雷击烧蚀损伤引起的材料力学性能退化模型. 采用连续损伤力学(CDM)方法提出了复合材料雷电烧蚀损伤的三维渐进损伤退化模型,采用Hashin和Yeh分层失效准则,验证了失效点的发生情景. 根据所建立的模型和刚度矩阵渐进损伤退化模型的编码,利用ABAQUS软件并结合UMAT子程序预测了拉伸载荷下雷电烧蚀损伤复合材料层合板的残余强度,最终的仿真精度验证了该模型的有效性.
英文摘要
    To characterize composite lightning ablation damage, mechanical material properties degradation model due to lightning strike ablation damage was presented based on the method of phenomenological analysis. A 3D progressive damage degradation model with lightning ablation damage on composites was constructed using the method of continuum damage mechanics (CDM), in which Hashin and Yeh delamination failure criteria were employed to verify the occurrence of failure point. According to the model constructed, residual strength of composite coupons with lightning ablation damage under tensile load was predicted through ABAQUS software combining the UMAT subroutine, which was coded by the stiffness matrix progressive damage degradation model. Tensile residual strength simulation accuracy demonstrates the ef?ciency of the constructed model.
