An accurate and easy to implement method for predicting matrix crack and plasticity of composites with an efficient search algorithm for LaRC05 criterion

A numerical method by combining extended Finite Element Method and anisotropic plastic model in ABAQUS is proposed to simulate matrix crack and plasticity of composites. The hydrostatic pressure sensitivity is introduced into the method by subroutine USDFLD based on Mohr-Coulomb theory. An efficient search algorithm is proposed for LaRC05 criterion, whose time cost is only 10% of that of original algorithm. Then, the accuracy of proposed method...
