A Nonlinear FE Analysis to Model Progressive Fatigue Damage of Cross-Ply Laminates under Pin-Loaded conditions - ScienceDirect
Involving several damages and failure mechanisms result in a rather complex fatigue process of composite materials. Inhomogeneity, anisotropy and nonlinear nature of composite materials require advanced nonlinear modeling techniques of strength and fatigue. In this paper, a progressive fatigue damage model is proposed by considering the nonlinearity effects of in-plane shear stress/strain relationship....
