Progressive Failure Analysis of Composite Laminates Subjected to Transverse Loading with Augmented Finite Element Method

In this paper, two-dimensional (2D) orthotropic augmented finite element method (A-FEM) is applied to account for progressive failure of composite laminates under transverse loading, which considers all major cracking modes (delamination, fiber kinking/rupture matrix cracking). High-fidelity simulations different stacking loading are implemented. Both predicted load−deflection curves and damage evolution in good agreement with that experimental results, demonstrates the numerical capability A-FEM. addition, influence sequence on mechanism also studied by sequence. Results show tensile crack bottom laminar always first mode laminate, subsequent propagation related ply orientation adjacent plies have a blocking effect propagation.
