6.2. Remarques#
Dans cette modélisation, on prend en compte le terme dû à la plasticité de transformation:
\({\dot{\epsilon}}^{\mathit{pt}}(Z,T)\ne 0\) lorsque \(\dot{Z}\mathrm{\ne }0\)
La solution de référence est obtenue par la résolution numérique du problème avec des éléments axisymétriques pour lesquels on impose la condition de déformations planes.
