Abstract:

In this paper, we study the Riemann problem for a system of nonlinear elasticity in a crystalline polymer model. The system contains a hyperbolic-elliptic situation and is hyperbolic degenerated in another region. We use the Liu-entropy condition to analysis the properties of all the basic waves, then we construct the solutions for the Riemann problem.

Key words: System of nonlinear elasticity, Mixed type, Riemann problem,  Liu-entropy condition
