Lagrange-Like Contact in ETA Plus User's Manual

摘要

This report describes the theory and implementation of a contact algorithm in the211u001eexplicit finite element code ETA. First a motivation of the choice of the method 211u001eis given. Theory of this method is described. The new input definition and the 211u001enew data sets are described. Implementation is given, following the different 211u001esubroutines. Tests and demos are shown to validate the algorithm. Finally results 211u001eare discussed and recommendations made concerning future developments.
