An Assessment of the Piezoelectric Ultrasonic Composite Oscillator Technique (PUCOT) for Measuring the Elastic and Technical Constants of Solids

CODEN: JTEVAB

Abstract

An assessment of the methodology of the piezoelectric ultrasonic composite oscillator technique (PUCOT) shows that the present PUCOT equations are invalid for anisotropic materials. The appropriate differential equations governing elastic waves propagating in thin rods are solved for the required relationships between the response resonant frequencies and the elastic constants. Experimental results for silver, aluminum, and copper single crystals, which have anisotropy factors of 3.1, 1.2, and 3.2, respectively, are presented to support the theoretical findings.
