Abstract
Based on the previous investigation on 2D moving and rolling contact problem
by BEM, the conforming discretization is extended to 3D cases, two schemes of
boundary element method for moving contact of 3D elastic solids using
conforming discretization is presented. Both the displacement and traction
boundary conditions are satisfied on the contacted region in the sense of
discretization. In this way the good characteristics of BEM can be preserved.
One scheme is proposed for the case of moving contact with prescribed moving
direction. Each element of triangular shape has three fixed nodes at the corners
of the triangular element, and three movable nodes on three sides of the element.
Another scheme is proposed for the cases with unknown, or variable moving
direction. Each element of triangular shape also has three fi
