Proper formulation of viscous dissipation for nonlinear waves in solids.
To model nonlinear viscous dissipative motions in solids, acoustical physicists usually add terms linear in Ė, the material time derivative of the Lagrangian strain tensor E, to the elastic stress tensor σ derived from the expansion to the third (sometimes fourth) order of the strain energy density E=E(tr E,tr E(2),tr E(3)). Here it is shown that this practice, which has been widely used in the...
متن کاملCluster Heating by Viscous Dissipation of Waves
We simulate the effects of viscous dissipation of waves that are generated by AGN activity in clusters of galaxies. We demonstrate that the amount of viscous heating associated with the dissipation of these waves can offset radiative cooling rates in cooling flow clusters of galaxies. This heating mechanism leads to spatially distributed and approximately symmetrical dissipation. The heating wa...
متن کاملZero-dissipation limit for nonlinear waves
Evolution équations featuring nonlmeanty, dispersion and dissipation are considered hère For classes of such équations that mclude the Korteweg-de Vries-Burgers équation and the BBMBurgers équation, the zero dissipation limit is studied Uniform bounds independent of the dissipation coefficient are denved and zero dissipation limit results with optimal convergence rates are established Mathemati...
متن کاملNonlinear transverse waves in deformed dispersive solids
We present a phenomenological approach to dispersion in nonlinear elasticity. A simple, thermomechanically sound, constitutive model is proposed to describe the (non-dissipative) properties of a hyperelastic dispersive solid, without recourse to a microstructure or a special geometry. As a result, nonlinear and dispersive waves can travel in the bulk of such solids, and special waves emerge, so...
متن کاملNonlinear Stability of Viscous Roll Waves
Extending results of Oh–Zumbrun and Johnson–Zumbrun for parabolic conservation laws, we show that spectral stability implies nonlinear stability for spatially periodic viscous roll wave solutions of the one-dimensional St. Venant equations for shallow water flow down an inclined ramp. The main new issues to be overcome are incomplete parabolicity and the nonconservative form of the equations, w...
