A numerical solution of the three dimensional frictionless contact problem and its data parallel implementation on the Connection Machine system CM-2 is presented. The numerical solution is obtained by means of boundary element discretization of a variational inequality and related extremum principle; the associated Green's function is approximated by means of standard direct boundary element procedure. A numerical method is applicable to any kind of geometry of the contacting bodies under arbitrary loading. The example presented illustrate a distinct ability of the method to capture the influence of the shape and the size of a body on the contact area and the pressure acting in it. It has been demonstrated that the symmetry properties of the Green's operator hold only asymptotically for the discretized problem. |
