ELASTIC-WAVES IN MEDIA WITH NONLINEAR DISSIPATION

The paper presents a rheological model that treats a medium with nonli near dissipation as a unidimensional chain of masses interacting throu gh linear and nonlinear inelastic links. In the framework of this mode l, we derived a nonlinear wave equation and studied such effects of pr opagation and interaction of elastic waves as self-action of continuou s harmonic and pulse waves, generation of higher order harmonics, and the effect of a strong wave on the attenuation of weak waves of other frequencies.
