The numerical solution of the three-dimensional frictionless contact problem is obtained by means of a boundary element discretization of a variational inequality and its related extremum principle. The discretization leads to a finite dimensional quadratic programming problem, solved by a modification of the gradient projection method. The associated Green’s function is approximated using a standard direct boundary element procedure. The numerical method is applicable to any type of contacting bodies geometry under arbitrary loading. The examples considered were chosen such as to illustrate a distinct ability of the method to capture the influence of a body shape on the contact area and pressure acting in it. It has been demonstrated that the symmetry properties of the Green’s operator hold only asymptotically for the discretized problem. |
