... The Adhesive Mechanism of Hysteretic Nonlinearity for Media with Cracks . ... The creation of models of different defects (dislocations, cracks etc.) and construction of state equations for solids containing such defects, is one of modern problems of nonlinear acoustics and seismic-acoustics. ... This circumstance creates favorable capabilities for nonlinear acoustic diagnostics of both single defects in solids, and solids containing a great number of such defects. ...

... The Behaviour of the Acoustic Gyrometers for Transient and High Rotation Rates . ... Acoustic rate gyros provide output signals that are measures of rotation rates with respect to an inertial frame. They involve both inertial and flow-induced acoustic modes coupling inside rotating cylindrical fluid-filled resonant cavities, the former occurring for transient and stationary rotation of the device, the latter occurring only for the transient rotation. ...
... The Chemical Consequences of Cavitation . ... High intensity ultrasound has found new applications in driving chemical reactions and in the preparation of unusual materials. The chemical effects of ultrasound originate from acoustic cavitation: the formation, growth, and implosive collapse of bubbles in a liquid. ... In otherwise cold liquids, ultrasound is able to drive reactions that normally occur only under extreme conditions. ...
