A new micro-mechanical model is developed to predict the behavior of unidirectional polymer matrix composite laminates under impact loading conditions and implemented in the non-linear finite element software LS-DYNA. This model accounts for the progressive post-failure behavior and strain-rate dependency of polymer matrix composites making it suitable for impact simulations. A continuum damage mechanics...
A new 3-D constitutive model is developed for finite element simulations of plain weave composites (PWC) structures and implemented in the explicit finite element software DYNA3D. The aim of this work is to develop a material model for PWC which incorporates their significant deformation characteristics like strain rate sensitivity, progressive failure phenomena, and nonlinearity in shear and yet...
