Determination of elastic moduli by the resonant ultrasound spectroscopy method
Kolman R., Plešek J., Landa M.
pages 162 - +9p., full text

An optimization method for the determination of elastic moduli by resonant ultrasound spectroscopy (RUS) was proposed. All components of the fourth-order tensor of elastic moduli for a general anisotropic material is determined from the knowledge of the resonance response (spectrum) of the mechanical system. This spectrum is obtained from experimental measurements, using the RUS method on the prismatic specimen. For the iterative computation of elastic moduli an identification algorithm based on the direct iteration method is used. Spatial discretisation is performed by the finite element method. The paper closes with test examples and discussion.
