I am interested in implementing a non-linear viscoelastic solid in Comsol multiphysics from its storage and loss moduli that follow a power law : G'(omega) = G0' * omega^alpha and G''(omega) = G0''* omega^alpha. However it seems impossible in Comsol multiphysics to use something else than well known linear viscoelastic models as Maxwell, Kelvin-Voigt, Burger...
