ABSTRAK
Variations in the thermodynamic state of a dispersive medium, caused by sound, are studied. A bubbly liquid and a Maxwell fluid are considered as examples. Curves in the plane of thermodynamic states are plotted. They are in fact pictorial images of linear relations of excess pressure and excess density in...

ABSTRAK
The nonlinear dynamics of perturbations, quickly varying in space, with comparatively large characteristic wavenumbers k k > 1/H, is considered. H is the scale of density and pressure reduction in unperturbed gas, as the coordinate increases H is the so called height of the uniform equilibrium gas. Coupling nonlinear equations...

This multi-contributed volume provides a practical, applications-focused introduction to nonlinear acoustical techniques for nondestructive evaluation. Compared to linear techniques, nonlinear acoustical/ultrasonic techniques are much more sensitive to micro-cracks and other types of small distributed damages. Most materials and structures exhibit nonlinear behavior due to the formation of dislocation and micro-cracks...

Gurbatov, S.N., author
Waves and structures in nonlinear nondispersive media : general theory and applications to nonlinear acoustics” is devoted completely to nonlinear structures. The general theory is given here in parallel with mathematical models. Many concrete examples illustrate the general analysis of Part I. Part II is devoted to applications to nonlinear...
