For the sake of characterizing composite lightning strike coupling damage, based on the method of continuum damage mechanics (CDM) and phenomenological analysis, stiffness matrix progressive damage degradation model of composite laminate structure with lightning strike ablation damage and mechanical impact damage was constructed in this paper. An effective three-dimensional finite element model (FEM) of composite laminate structure with lightning strike coupling damage has been established based on ABAQUS software, and combine UMAT subroutine, which was coded by stiffness matrix progressive damage degradation model, strength prediction and failure process analysis were accomplished under tensile load. Excellent agreement between experimental data and numerical results is observed. The results indicate that models constructed in this paper can characterize the lightning strike coupling damage well, and have the abilities to predict the residual strength and failure process of composite laminate with lightning strike coupling damage.
