A spectral element method for the numerical analysis of 2D and 3D wave propagation problems is equipped with a viscoplastic constitutive model in order to provide a tool able to grant the flexibility of a finite element technique in dealing with non linear constitutive models, together with the accuracy of spectral methods for propagating waves. The proposed tool is both fast and behaves like a black-box requiring minimum interaction to the user. The implementation of the method is illustrated and applied to a set of 2D reference cases.
