Stressed state of elastic plane with cavities

An algorithm for the numerical solution of the problem of defining the stressed state of a loaded plane with cavities of arbitrary configuration is given. A system of singular integral equations is given, which is obtained by using displacement potentials, is quantizied by the method of discrete singularities and finite differences. Existence and uniqueness conditions for solutions are formulated. The algorithm is debugged on a test example and is applied to a study of interrelation of elliptic cavities when the distance between them decreases.Translated from Dinamicheskie Sistemy, No. 7, pp. 8–13, 1988.
