Structural analysis of durability of macroheterogeneous solids under plane stress state

The authors propose a method, basеd on the structural approach, for construction of a surface of resistance, in an interspace of characteristics of external action. The authors take into account physical correlations for a composite material which take into account the correctly formulated boundary conditions at the interface between phases. A nu-merical analysis is performed to study the effect of anisotropic properties of the substructural elements, their strength, volume fraction, and relative position, on the rupture of a composite material.
