This paper on "Algorithms for Large Strain Contact and Impact Analysis Using LUSAS" was presented at the 3rd International Conference on Quality Assurance and Standards in Finite Element Analysis - 10-12 September 1991, Stratford-upon-Avon, England.

Summary

This paper outlines some of the recent developments that have been implemented in the LUSAS finite element system for the solution of finite strain elastoplastic contact/impact problems. The paper focuses on three areas: implementation of an contact procedures, suitable clement formulations and integration of the constitutive equations. Four examples are then presented to illustrate the effectiveness of the new procedures.
