Abstract
A multiscale numerical procedure has been developed by implementing a 3D rate dependent inelastic micromechanics model within the nonlinear transient finite element code LS-DYNA to investigate high velocity impact of polymer matrix composite laminates. A recently developed strength of materials based 3D micromechanics model, incorporating a set of nonlinear, strain rate dependent constitutive equations for the polymer matrix, has been extended to model through the thickness normal stresses and transverse shear stresses that are critical during impact events. A progressive damage model is used to identify various failure modes associated with the penetration process. Good correlation has been obtained between predicted and experimental results.
