Abstract: | An algorithm is proposed to determine the effective deformation properties and stress-strain state of particulate composite
materials with physically nonlinear components and complex stress state. The laws that govern the deformation of particulate
composites are studied. A particulate composite is considered a two-component material of random structure. Its effective
properties are determined by conditional averaging. The nonlinear equations that incorporate the physical nonlinearity of
the components are solved by the method of successive approximations. The relationship between macrostresses and macrostrains
is established. The effective deformation properties of a particulate composite as a function of the volume fractions of the
components and stress state are studied
