Existence of Global Entropy Solutions to an InhomogeneousElastodynamics Equations
一类非齐次弹性力学方程组整体熵解的存在性

The existence of global entropy solution for nonlinear and inhomogeneous elastodynamics equations. A prior $L^{\infty}$ estimates of viscosity solution is derived with the help of the theory of invariant regions. By using the vanishing viscosity method together with compensation compactness theory, the convergence of viscosity solution is obtained.
