Two-and three-dimensional frictional contact problems are uniformly formulated as a system of nondifferentiable equations based on variational inequality theory. Through constructing a simple continuously differentiable approximation function to the non-differentiable one, the smoothing Newton metho

## Abstract We construct a novel __hp__βmortar boundary element method for twoβbody frictional contact problems for nonmatched discretizations. The contact constraints are imposed in the weak sense on the discrete set of GaussβLobatto points using the __hp__βmortar projection operator. The problem
A new finite element solution method for the analysis of frictional contact problems is presented. The contact problem is solved by imposing geometric constraints on the pseudo equilibrium configuration, defined as a configuration at which the compatibility conditions are violated. The algorithm doe
