In this paper the contact problems including frictional effects are presented. Contact between two deformable bodies is considered in general. The present approach, based on the Coulomb’s frictional law, elastic-plastic tangential slip decomposition and consistent linearization results in quadratic rates of convergence with the help of the Newton-Raphson iterative solution scheme. The results for the verification example are also presented.

Key words: contact problem, contact strain, friction, finite elements, penalty method, nonlinear analysis.
