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
