The assumption is accepted that inclusions are in an ideal or nonideal mechanical connection with the environment. The model proposed enables the plastic deformation study along the surface of the inclusion (plastic exfoliation) and in internal medium (it is accepted that plastic zone simulated as the cluster of random strips). The influence of the thickness of thin inclusions on the shape and on other characteristics of the plastic zones is analyzed. The estimate of simulation of thin inclusions as mathematic cut with stress jump is given. The characteristics of plastic zones in the bodies with notches inclusions of various shapes and configurations are determined. The mutual effect of stress concentrators on the development of plastic zones and on the plastic inclusions exfoliation is studied. The reasonable criteria for the applicability of the linear theory of elasticity for the plastic zones characteristic at an early stage of development is proposed.
