@article{11232, author = {Marie Rognes and Ragnar Winther}, title = {Mixed Finite Element Methods for Viscoelasticity With Weak Symmetry}, abstract = {Small deformations of a viscoelastic body are considered through the linear Maxwell and Kelvin-Voigt models in the quasi-static equilibrium. A robust mixed finite element method, enforcing the symmetry of the stress tensor weakly, is proposed for these equations on simplicial tessellations in two and three dimensions. A priori error estimates are derived and numerical experiments presented. The approach can be applied to general models for linear viscoelasticity and thus offers a unifed framework.}, year = {2010}, journal = {Mathematical Models and Methods in Applied Sciences (M3AS)}, volume = {20}, number = {6}, pages = {955-985}, doi = {10.1142/S0218202510004490}, }
