| contents | In the one-dimensional isothermal case, we introduce a simple model of nonlinear viscoelasticity within the Rational Extended Thermodynamics (RET) framework. The differential system is determined by the universal principles of RET, exhibiting symmetric hyperbolic form and ensuring the existence of smooth solutions for appropriately small initial data. In the linear case, the equation for viscous stress reduces to the well-known Maxwell model, thereby representing a plausible nonlinear extension of the Maxwell-type model. The total stress instead satisfies a non-linear Zener model. |
