The objective of this research is to model the three-dimensional                dynamic crack growth and failure mechanism in a composite laminate              subjected to low velocity impact.  This study will incorporate                  variationally consistent fracture mechanics elements, multi-failure             criteria and parallel processing algorithms.                                    The computational results will be checked with experimental data for            low velocity impacts of an object on the surface of a composite panel           and a cylinder.  The resultant code will provide a quantitative                 design tool for predicting composite laminate failure under low                 velocity impact.
