Abstract:

The present paper describes the parallel algorithm for explicit time integration with efficient nonlocal material model support, within the framework of finite element method. A central difference method is used to discretize equation in time and the application of both dual partitioning techniques (node-cut and element-cut) is discussed. The efficiency of the proposed algorithm is demonstrated by 3D analysis on a PC cluster.
