An Explicit Multi‐Body Contact Algorithm

Abstract

For the reliable and efficient solution of multi‐body contact problems involving large nonlinear deformations, an explicit time integration scheme is considered. For this kind of algorithms, a semi‐implicit approach for fulfillment of the contact constraints is presented. To apply this method to three‐dimensional problems, the solution of local equilibrium problems is required at the contact surface. An iterative form of the proposed scheme is used to decrease computational effort. Also some remarks are given with respect to contact detection.
