Abstract

A partial material replacement causes stress redistribution in comparison to the original structure made of a homogeneous material. The article presents a possibility to design a geometry of the replacement which keeps the state of stress unchanged. It is shown that for a class of two-dimensional configurations, it is possible to find a solution of this problem. Conditions for the existence of an appropriate geometry are given. A method to obtain the shape of the replaced part is proposed.
