Abstract
We present a study of accuracy and execution speed using a novel implementation of a nonlinear anisotropic fiber-reinforced material model within a Total Lagrangian Explicit Dynamic (TLED) finite element (FE) framework, developed for execution on Graphics Processing Units. Full integration and selective-reduced integration have been developed for tri-linear hexahedral elements and tested in comparison to the classical under-integrated TLED scheme. Comparison is performed with respect to an established FE code. Results indicate that by using the presented method, excellent accuracy can be retained while greatly accelerating solution times.
