A strain energy based failure criterion for nonlinear analysis of composite laminates subjected to triaxial loading

A new strain energy based failure model is developed for fibrous composite laminates under multi-axial loadings, taking into account the effect of hydrostatic stress. A failure mode dependent exponential stiffness reduction model is used to predict material response beyond the initial failure. Predi...
