| Abstract Scope |
Resonant ultrasound spectroscopy (RUS) is a powerful nondestructive evaluation (NDE) technique allowing for precise measurement of the elastic constants of a given material. Recently developed finite element (FERUS) techniques, which will be reviewed, allow for the determination of properties on samples with complex geometries. This contrasts with the simple and very computationally efficient set of functions determined by Visscher et al., which have been traditionally utilized, allowing for the general solution to be easily determined for simple geometries (right parallelepipeds, right cylinders, and spheres). This process assumes a certain level of geometric precision in the sample. In this study we determined the error associated with deviations from the ideal through the systematical evaluation of imperfect geometries using finite element (FERUS) techniques. An overview of the RUS technique along with how FERUS has allowed for elastic modulus measurement to be made on cladding material, in their final form, will be discussed. |
