摘要：
A theoretical model for the assessment of the yield strength of a granular composite material with a porous matrix has been developed. Parametric analysis of the model has been made; the effect of the loading type, porosity of the matrix material, and volume content of rigid inclusions on the macroscopic yield strength of the composite has been studied. An expression of the plasticity potential for a porous matrix composite, which provides a satisfactory agreement with the results of a numerical analysis of the model over the whole range of structural parameters variations, has been derived. The applicability of the developed approach to the investigation of making blanks of products from composite materials has been shown.
