The present paper deals with parallelization of explicit time stepping
algorithm in a general finite element environment.
Particularly, support for nonlocal constitutive models has been
considered. A central difference method has been used to discretize the
governing equation in time. Modifications of both node-cut and element-cut strategies
have been developed to provide efficient support for nonlocal constitutive
models. Efficiency of the proposed approach is demonstrated on
different hardware platforms.
