Abstract
A nonlinear elastic isotropic body model is proposed to describe the m echanical behavior of a powder composite material with different prope rties under tension and compression. The composite is considered as a three-phase body with an elastic matrix, throughout the volume of whic h pores and rigid inclusions are distributed. The unsymmetrical proper ties of this material are connected with the nucleation of defects, in particular with decohesion or the formation of discontinuities at the matrix-inclusion interfaces.
