# Evolution Equations and Reduction Approaches for Nonlinear Waves in Solids

## Abstract

We outline some theoretical procedures which permit to get an insight into the nonlinear structure of mathematical models of interest in wave propagation. First, by assuming the original governing system of first order PDE’s to take into account dissipative effects of different order of magnitude, we derive for the wave amplitude the evolution equation which, in same cases, involves a hierarchy of nonlinear wave operators. Later we focus our attention on developing reduction techniques in order to find out exact solutions to quasilinear nonhomogeneous systems of first order involving two dependent and two independent variables.
