Resonance Acoustic Spectroscopy deals with the analysis ofwaves generated in an elastic body by a plane harmonicacoustic wave. It is the first monograph to treat newanalytical and experimental methods for the investigation ofthe excitation, propagation and re-radiation of elasticwaves in solid, thick-walled and thin-walled elasticscatterers.The material is presented systematically,comprising the formulation of the problem, method ofsolution, algorithm, computation and analysis. A largenumber of computational results are given in the form ofmodal resonances, form functions, dispersion curves andacoustic spectrograms. Particular attention is paid to theinterpretation of the solutions.
