From the mesomechanical point of view, the internal structure of a material considerably influences its plastic deformation pattern at the meso-scale level. Structural effects in real materials are threedimensional. It is a challenge to perform 3D-modeling for material behavior under loading, taking into account an internal structure. In this paper, a special routine is applied to generate a 3D polycrystalline structure. A dynamic problem is solved to calculate 3D-polycrystal behavior under plane shock wave using a finite-difference approximation. The results of 3D simulations are analyzed and compared with those obtained in the framework of a 2D formulation.
