No rating yet Subject: Re: [STRUC] Bonded contacts Author: Bram Weisman Date: 2008-05-02 21:20:44I don't know how much help this will be, but I would recommend you read the on-line documentation "Contact Technology Guide" in it's entirety. Along the way you should find some clues. Be aware that there are several algorithms to choose from when doing bonded contact, some are stiffness and/or penalty function based, and others are constraint equation based (MPC).

Hello everyone, This is my first post; I hope I have done everything properly... My question is about bonded contacts: I have looked everywhere I could think of (ansys help, google, library...), but I haven't been able to find the mathematical description of these elements, only that of standard contact elements. So what does Ansys do to keep those bonded elements from opening? Is it a restriction on allowed nodal displacement? Like, they can't move out of the pinball region, or can't move relative to one another (target nodes vs contact nodes)? If anyone has any suggestions (or references I could check) to shed some light on this... thanks! Christiane Caouette, jr eng. PhD Student at Ecole de Technologie Superieure
