Abstract:
On the basis of experimental data of the study of amplitude-dependent internal friction
phenomena in polycrystalline solids the inelastic hysteretic state equation with a saturation of
nonlinear losses is proposed. Theoretical analysis of the asymmetric saw-tooth waves propagation
in such media is carried out. The regularities (amplitude dependent losses and changes in the
propagation velocity) are determined for the characteristics of nonlinear wave and its higher
harmonic amplitudes. The graphical analysis of form of the wave and evolution of its spectral
components is carried out.
Keywords:
hysteresis, amplitude-dependent internal friction, saturation of nonlinear losses, saw-tooth acoustic waves.
