Abstract
A synergistic damage mechanics approach was implemented into a commercial finite element package to predict progressive failure of multidirectional polymer composite laminate components. The methodology retains the framework of continuum damage mechanics, while incorporating micromechanics to define the internal damage variables of the material system computationally. A user-defined subroutine was developed and damage evolution of quasi-static tensile loaded components was simulated using nonlinear analysis. The model predictions were in good agreement with experimental observations reported in the literature. Future considerations for model development should include incorporating the effects of multiaxial stresses on damage evolution, and adding additional damage modes to the model.
