Abstract

Recently, interior point methods are focused as an efficient strategy for large scale contact problems. In this paper, we present a method based on a predictor-corrector method for contact problems with multi-point constraints. Furthermore, we implement our algorithm into FrontISTR, which is an open-source and large scale finite element structural analysis software, and investigate the performance.
