Abstract

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