Nonlinear Waves in Solids Generated by Impact

Abstract

The final report summarizes contributions of research supported by the project. There are three main areas: (1) Classification of 2x2 non-strictly hyperbolic systems. (2) Wave curves with the presence of an umbilic point and an umbilic line. (3) The generalized Riemann problem. The results are of general nature that they are applicable not only to nonlinear isotropic elastic solids bur also to other areas such as the oil recovery problems.
