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
