Problems in Nonlinear Acoustics: Surface Acoustic Waves, Diffracting Sound Beams, and Fluid-Solid Interface Effects.
Abstract
Three subject areas, with emphasis on nonlinear acoustics, are discussed in this annual summary report: (1) Surface Acoustic Waves (evolution equations, generalized model equations for complex space-time dependencies, and nonlinearity coefficients for Rayleigh waves, and model equation for Stoneley waves); (2) Diffracting Sound Beams (modeling of noise and relaxation, measurements of focused beams, and transient solution for radiation from a parabolic antenna); and (3) Fluid-Solid Interface Effects (comparisons of 2-D and 3-D reflection for piston and Gaussian sources).
