Description	Mori-Tanaka approach is used to modelling metal particulate-reinforced brittle matrix composites under cyclic compressive loading. The J2 flow theory is considered as the relevant physical law of plastic flow in inclusions. A strong constraint exerted by matrix on inclusions causes that even the evanescent kinematical hardening rule does not predict any ratchetting of a composite. It is shown that the weakening constraint of the matrix caused by microfracture damage around inclusions is closely coupled with the plasticity of inclusion and leads to ratchetting even when the plastic deformation of inclusions is described by an isotropic hardening rule. A detailed parametric study has revealed that ratchetting is followed by either plastic or elastic shakedown, depending on the load amplitude, composite parameters and the mean microcracks length.
