Based on lectures by the author, this volume is designed as a textbook on general ultrasonics. The text provides coverage of the propagation of ultrasonic waves in media with different elastic properties and under conditions close to those encountered in scientific and practical applications of ultrasound. As well as classical material and data from original sources, the book includes experimental data on the velocity of sound in isotropic solids and crystals. Each chapter is complemented by problems and their solutions.
Basic equations of the theory of elasticity; propagation of ultrasonic waves in liquids and gases; sinusoidal plane waves with infinitesimal amplitude; numerical examples - the logarithmic scale of intensities and amplitudes; finite-amplitude plane waves; steady forces arising in an ultrasonic field; ultrasonic cavitation; reflection, refraction and scattering of ultrasonic waves; transmission of plane waves through layers - electroacoustical analogies - radiation of plane waves; spherical waves; propagation of ultrasound in an isotropic solid; propagation of ultrasound in crystals.
