| Abstract: | — Godunov's method, a numerical method for solving conservation laws, is applied to nonlinear and inelastic wave propagation in soil. The solution is restricted to the one-dimensional case. An approximate Riemann solver for Godunov's method is presented. The capability of the numerical method is shown by a comparison with the analytical solution of a linear inelastic wave propagation. Finally the behaviour of the nonlinear inelastic soil is described by a hypoplastic constitutive law. |
