|
Abstract:
为了对含雷击热-力耦合损伤复合材料层压板的剩余强度进行预测，基于连续介质损伤力学法（CDM）和唯象分析法，建立了表征复合材料雷击热-力耦合损伤的刚度矩阵渐进损伤退化模型。基于该模型，通过ABAQUS有限元仿真软件，建立了含雷击热-力耦合损伤的复合材料层压板结构三维模型。结合UMAT子程序，完成了拉伸载荷下的剩余强度预测。结果表明：通过与试验对比，仿真结果与试验结果取得了良好的一致性。本文所建立模型，能够有效进行含雷击热-力耦合损伤复合材料层压板结构拉伸剩余强度预测。 For the sake of predicting residual strength of composite laminate with lightning strike thermal-mechanical coupling damage, stiffness matrix progressive damage degradation model was constructed to characterize composite lightning strike thermal-mechanical coupling damage based on continuum damage mechanics (CDM) method and phenomenological analysis method. An three dimensional model of composite laminate structure with lightning strike thermal-mechanical coupling damage was established based on progressive damage model and ABAQUS finite element simulation software. Combined with UMAT subroutine, residual strength prediction was accomplished under tensile load. The results show that excellent agreement between test data and numerical results is observed. The model constructed in this paper is capable to predict the tensile residual strength of composite laminate with lightning strike thermal-mechanical coupling damage. 国家自然科学基金（51477132）
