Let us pass to the consideration of certain plane problems of micropolar elasticity in which the stress concentrations are not caused by a singular load distribution but by a special form of the loaded body. The simplest and perhaps the most important and widely known example of such a stress concentration is encountered when a plane sheet or plate subject to arbitrary plane state of strain (or stress) contains an inclusion made of a different material. Two limiting cases can be considered here: if the material of the inclusion is assumed to be perfectly rigid then the boundary conditions at the interface between the original material and the inclusion are very simple; the inclusion does not deform and behaves as a rigid body; the displacements of the original material at the boundary of the inclusion either are zero or reflect a possible rigid translation and rotation. It is assumed that both materials are glued together fulfilling thus the continuity conditions before and after deformation.
