Resonant Ultrasound Spectroscopy in Complex Sample Geometry: Author: Fig, Matthew Kenneth; Date: 2005-12-15; Program: Mechanical Engineering; Abstract: Resonant Ultrasound Spectroscopy (RUS) is the study of the mechanical resonances, or normal modes, of elastic bodies to infer material properties such as the elasticity matrix. This powerful technique is based on two physical facts, the first of which is that the resonant response of an elastic object depends on several parameters intrinsic to the object, such as the object's shape, density, elastic constants, and crystallographic orientation. The second is that using these parameters, the resonant spectrum of an object can be calculated. This method has widely been applied to rectangular para...; Download File | View full details
