Development and Evaluation of Ultrasonic Piezoelectric Transducers for the Determination of Dynamic Young's Modulus of Triaxially Loaded Rock Cores
Equipment has been developed that enables the rapid determination of dynamic Young's modulus of triaxially loaded rock cores. Measurement of dynamic modulus is based on a pulse propogation technique using piezoelectric transducers. A detailed description is given of the development of the equipment suitable for laboratory investigations. Details of a laboratory study investigating the variation between static and dynamic moduli of triaxially loaded rock cores are given.
