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.
