Isogeometric Analysis for the numerical simulation of rubber structures

S. Lejeunes

Résumé

In this work, we propose to discuss about the interrest of the Isogeometric Analysis as a computational framework for the numerical simulation of rubber structures with a multi-field approach. We show that we can construct stable approximations for hyperelastic problems using the same approach as that used for finite-elements. We also show that the extension to thermo-mechanical problems is very simple. Using simple numerical examples and the same variationnal formulation, we compare the numerical performance of IGA and FE.
