A structural theory of the coupled processes of deformation and short-term damage is set up for the following materials whose stress–strain curves have a descending portion: homogeneous physically nonlinear materials and particulate composites with two physically nonlinear components. Damage is modeled by randomly arranged micropores formed in place of damaged microvolumes. The short-term damage criterion for a microvolume is a strain-based failure criterion formulated in terms of the second deviatoric microstrain invariant. The effect of microstrength distribution functions on the deformation and damage of a homogeneous material and the effect of the volume fraction of inclusions on the deformation and damage of a particulate composite are studied
