A three-dimensional elastic contact problem is examined. It is assumed that the displacements and deformations are small and the supposed zone of the contact domain must be single-connected, and surrounded by a smooth closed curve. The closed curve is interpolated by a single closed spline. For numerical tests three-dimensional p-extension finite elements are used. To take the conditions of contact and separation into account the penalty method is applied. Numerical examples presented here show the effect of positioning 3D p-version elements along the contact-separation and/or stick-and-slip borders and the influence of the friction coefficient, respectively.
