Abstract

Experimentation at Wayne State University has lead to the development of a quasi acousto-ultrasonic method that utilizes an acoustic perturbation in the test region to enhance the dispersion of energy in the frequency domain. Analytical modeling has been used to explain this energy redistribution on two crucial levels; harmonic frequency generation, and sideband generation through amplitude modulation. Further refinement in both testing and modeling is planned.
