Physically interesting phenomena appear when sound amplitude is increased to be finite. For example, such a sound deforms its waveform during propagation and shock front forms finally. This means that frequency components that do not exist originally are newly created. There are various interdisciplinary research fields branches that treat nonlinear acoustics. Sonic booms and earthquakes are undesired phenomena in nonlinear acoustics; nondestructive testing and biomedical ultrasonic therapy are practically applied in industrial and medical fields; sonochemical reaction due to cavitational collapse can be used for initiation or enhancement of catalytic reaction; thermoacoustic systems have a promising potential for solving global heat problems. This book provides a useful resource and current reference for scientists and engineers who actually work on or are interested in such problems in nonlinear acoustics.

Nonlinear Acoustic Waves in Micro-inhomogeneous Solids covers the broad and dynamic branch of nonlinear acoustics, presenting a wide variety of different phenomena from both experimental and theoretical perspectives. The introductory chapters, written in the style of graduate-level textbook, present a review of the main achievements of classic nonlinear acoustics of homogeneous media. This enables readers to gain insight into nonlinear wave processes in homogeneous and micro-inhomogeneous solids and compare it within the framework of the book. The subsequent eight chapters covering: Physical models and mechanisms of the structure nonlinearity of micro-inhomogeneous media with cracks and cavities; Elastic waves in media with strong acoustic nonlinearity; Wave processes in micro-inhomogeneous media with hysteretic nonlinearity; Wave processes in nonlinear micro-inhomogeneous media with relaxation; Wave processes in the polycrystalline solids with dissipative and elastic nonlinearity caused by dislocations; Experimental studies of the nonlinear acoustic phenomena in polycrystalline rocks and metals; Experimental studies of nonlinear acoustic phenomena in granular media; and Nonlinear phenomena in seismic waves are dedicated to the theoretical and experimental research of nonlinear processes, caused by longitudinal elastic waves propagation and interaction in the micro-inhomogeneous media with a strong acoustical nonlinearity of different types (elastic, hysteretic, bimodular, elastic quadratic and non-elastic). This valuable monograph is intended for graduate students and researchers in applied physics, mechanical engineering, and applied mathematics, as well as those working in a wide spectrum of disciplines in materials science.
