Prykladni Problemy Mekhaniky i Matematyky| Резюме: | A numerical algorithm has been developed for solving a frictional contact problem concerning the interaction of a layer with punches of complex shapes. The algorithm is based on the application of the integral equation method and reduction to a quadratic programming problem. The kernels of the integral equations are derived using the fundamental solution for a layer, represented in a compact analytical form. The contact problem with an unknown contact region is formulated in terms of Signorini-type integral equations-inequalities. By employing cubature formulas, the problem is discretized into a system of linear algebraic equations-inequalities, which is subsequently transformed into a quadratic programming problem. The efficiency and applicability of the developed algorithm are demonstrated through the analysis of frictional contact interactions between the layer and punches of various shapes. Cite as: O. I.
