An algorithm for solving two dimensional moving contact problems using conformational discretization is presented using the BEM to solve the inherently nonlinear boundary contact problems. A special boundary element is utilized in the algorithm to simultaneously satisfy the displacement compatibilities and the traction equilibrium conditions at the contact interface. In addition, a method is presented to flexibly move the contact boundary location on the possible contact boundary. The method is effective for solving the moving contact problem over a larger possible moving contact region.
