Accuracy analysis of the solution of spatial contact problem by means of the FEM

Abstract

In the work was a solved contact interaction problem of elastic hemispheres which has the form of Hertz – Beliaev solution. The solution of the same problem by means of FEM is simultaneously examined. Errors of the solution for various FE meshes are determined. Techniques of semi automatic generation of the FE meshes for reducing an error of the problem educetion are developed.
