Abstract
In this contribution, a mesomechanical approach to simulate the elasto-plastic behavior of heterogeneous media with explicit consideration for the material structure has been extended to the three-dimensional case. Polycrystalline and metal matrix composite structures have been designed via a special method developed in our earlier work. Three-dimensional simulations of elasto-plastic deformation of the structures under tension have been performed by the finite difference approximation technique. The results of the 3D-calculations have been analyzed and compared with those obtained from the 2D-approximation. The analysis of the 3D structure behavior at different scale levels is made on the base of the mesomechanical concept.
