Abstract
A contact detection algorithm using Overhauser spline was used, solving contact problems
with finite element method. Contact area defined by objects boundaries could be approximated
in different ways. It can be modelled using straight lines between nodes, finite element shape
functions or interpolation functions over boundary nodes respectively. As line description gives
a poor approximation of the boundary, shape functions are widely used to describe the
analysed geometry. C° inter-element continuity of the geometry description is provided by the
isoparametric elements. As the 'smooth' and accurate geometry description is crucial to contact
stress analysis, decoupling of the geometry from the polynomial shape functions and
implementation of the Overhau
