Acoustic waves in media with hysteretic nonlinearity and linear dispersion

A hysteresis equation of state is proposed for polycrystalline solids with saturation of nonlinear losses. Effects of amplitude-dependent internal friction and higher harmonic generation that result from propagation of harmonic acoustic waves in rods made of such materials are theoretically and nume...

Zusammenfassung:	A hysteresis equation of state is proposed for polycrystalline solids with saturation of nonlinear losses. Effects of amplitude-dependent internal friction and higher harmonic generation that result from propagation of harmonic acoustic waves in rods made of such materials are theoretically and numerically studied.
