In this paper, the energy and momentum conserving algorithmic paradigm is extended to encompass a phenomenon featuring physical dissipation: dynamic frictional contact. Whereas in other works dealing with conservative systems the chief aim is often the maintenance of numerical stability in the non-l
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
## a b s t r a c t In this paper, we focus on the variational inequality problem. Based on the Fischer-Burmeister function with smoothing parameters, the variational inequality problem can be reformulated as a system of parameterized smooth equations, a non-interiorpoint smoothing method is present
