Description	Brittle solids fail in compression by a process of progressive microfracture. If subjected to cyclic loading beyond the elastic range with nonzero mean stress, usually there is a cycle by cycle accumulation of inelasticstrain related to microfracturing in the direction of mean stress similarly like an accumulation of plastic strain in steels or other metals. This phenomenon is called cyclic creep or ratcheting. Using a suitable composite approach a response of representative volume element of composite may be modeled. It is proposed that the weakening constraint power of the matrix caused by microfracture damage around inclusions can reconcile the model predictions with experiment. introduce a microfracture damage by an approximative, self-consistent method. The microfracture damage is closely coupled with the plasticity of inclusions and provides additional inelastic strains. Numerical results are presented and compared with experimental data.
