ABSTRACT:
A method and apparatus for predicting the shape of a contact region of a finite element model deformed against a contact surface. The contact surface may be a rigid body or another finite element model. The shape of a contact region is dictated by the node/element distribution in response to a simulated load. This procedure uses curve fitting to predict the boundary of a contact region for a specified load condition based upon an analysis of contact region shapes generated by finite element analysis for each load within a range of simulated loads. In this manner, the discrete nature of the contact region boundary associated with finite element analysis results at a single load is overcome using information derived from previous load simulations. The approach improves the accuracy and resolution of simulated contact shape boundaries without a corresponding increase in processing resources.
