Abstract

Moving and rolling contact of 2D elastic bodies with defects using boundary element method Z. Yao, J. Pu Department of Engineering Mechanics, Tsinghua University, China Abstract A scheme of boundary element method for moving contact of two- dimensional elastic bodies using conforming discretization presented by authors is briefly formulated at first. In the scheme both the displacement and the traction boundary conditions are satisfied on the contacted region in the sense of discretization. An algorithm to deal with the moving of the contact boundary on a larger possible contact region is presented. The algorithm can be generalized to rolling contact problem as well. Some numerical examples of moving and rolling contact of 2D elastic bodies with or without friction, including the bodies with a hole-type defect are given to show the effectiveness and the higher accuracy of the presented schemes. Finally, numerical examples of moving contact of 2D elastic bodies with a crack in
