Problems in Nonlinear Acoustics: Surface Acoustic Waves, Nondestructive Testing,and Acoustic Streaming

摘要

Three projects in nonlinear acoustics are described: (1) Surface Acoustic Waves(derivation of theoretical models for Stoneley and Scholte waves in isotropic solids, surface waves in crystals, and surface waves in piezoelectric materials); (2) Nondestructive Testing (theory and experiment for ultrasonic measurement of third order elastic moduli via immersion techniques); and (3) Acoustic Streaming (numerical modeling of acoustic streaming, at high Reynolds numbers, produced by focused sound beams containing shocks).
