The unified approach for the analysis of elastic equilibrium of solids containing thin internal and surface heterogeneities

This paper develops the unified approach for the analysis of plane elastostatic problems for solids containing thin elastic inclusions or overlays. The approach is based on the previously developed integral equation method for the solution of plane elastostatic problems for solids with perfectly embedded inclusions. In this paper the method is extended to the case of delaminated inclusion and elastic enforcing overlay. Thus, the wide class of problems can be solved basing on the developed technique.
