Convergence analysis of XFEM methods for a nonlinear viscoelasticity constituve law
Résumé
The purpose of this note is to describe and compare some extended finite element approximations and their convergence for crack rubber-like materials. The analysis is based on the finite plane deformation visco-hyperelasticity theory for an incompressible Mooney-Rivlin material. Numerical examples show that for well chosen enrichment strategies, the finite element converges with the expected convergence order. Finally we discuss the numerical results we obtain.
