Summary: We investigate a \(H^1\)-Galerkin mixed finite element method for nonlinear viscoelasticity equations based on \(H^1\)-Galerkin method and expanded mixed element method. The existence and uniqueness of solutions to the numerical scheme are proved. A priori error estimation is derived for the unknown function, the gradient function, and the flux.
