<h2><span class="mw-headline" id="Limitations">Limitations</span></h2>

<ol><li>La contrainte de contact est seulement appliquée entre deux faces.</li></ol>
|
|
<h2><span class="mw-headline" id="Notes">Notes</span></h2>
|
|
<ol><li>La rigidité du contact doit être 10 fois plus tendre (young's modulus) que le modulus pour avoir un contact dur. Plus la valeur de la rigidité du contact est élevée, plus le contact entre les surfaces est difficile.</li>
|
|
<li>La face esclave est la face qui pénètre dans la face maître, et présente donc plus de déformation.</li>
|
|
<li>La carte *CONTACT PAIR est utilisée pour modéliser le contact dans CalculiX. La contrainte utilise le contact de pénalité face à face et la formule du contact est expliquée en détail ici <a rel="nofollow" class="external free" href="http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node112.html">http://web.mit.edu/calculix_v2.7/CalculiX/ccx_2.7/doc/ccx/node112.html</a></li></ol>
