Description:... The generalized forces associated with the mathematical model are obtained from non-convex superpotentials by forming the local subdifferential of the superpotential at the given point. The complementary equations are obtained by introducing pseudo-potentials of dissipation and applying in these potentials the hypothesis of normal dissipation. Because of the lack of differentiability of these superpotentials and pseudo-potentials, we employ a regularization methods where a smoothing procedure is applied
