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
