| Abstract: | Three dimensional frictional contact problems are formulated as linear complementarity problems based on the parametric variational
principle. Two aggregate-function-based algorithms for solving complementarity problems are proposed. One is called the self-adjusting
interior point algorithm, the other is called the aggregate function smoothing algorithm. Numerical experiment shows the efficiency
of the proposed two algorithms.
