The aim of this article is to simulate the viscoelastic behaviour during quasi-static equilibrium processes using the software Comsol Multiphysics. Two-dimensional constitutive equations of the three most classical rheological models (the Kelvin-Voigt, Maxwell and Three-Elements models) are developed and the mechanical equations for each model are rewritten to be compatible with the predefined Comsol format in the so-called Coefficients mode. Results of the simulations on creep and relaxation tests are compared with experimental data obtained on a sample of biological tissue.
