USE OF THE INDIRECT BOUNDARY ELEMENTS METHOD FOR ISOTROPIC PLATES ON AN ELASTIC WINKLER BASE AND PASTERNAK — VLASOV BASE

Abstract

The calculation tasks combining lightness, economy, high strength and reliability of thin-walled structures on an elastic base are relevant for modern mechanical engineering. In this regard, the use of isotropic materials on an elastic base seems justified, therefore their calculation is considered in this article. The problems of the theory of plates and shells belong to the class of boundary value problems, the analytical solution of which, due to various circumstances (the nonlinearity of differential equations, the complexity of geometry and boundary conditions, etc.), cannot be determined. Numerical methods help to solve this problem. Amongnumerical methods, undeservedly little attention is paid to the boundary element method. In this regard, the further development of indirect compensating loads method for solving problems of the theory of isotropic plates on an elastic base of Winkler and Pasternak Vlasov, based on the application of exact fundamentalsolutions, is relevant.
