Abstract : The following admissibility criterion for solutions of hyperbolic conservation laws is proposed: A weak solution is admissible if the total entropy decays with the highest possible rate. The equivalence of this criterion and viscosity criterion is established for the single equation and the system of equations of one dimensional nonlinear elasticity. (Author)
