A method of ultrasonic resonance is used to determine the elastic constants of isotropic cylinders. As applied in this study, this method implies simultaneous application of approximate techniques to solve for the equations of motion of the cylinder and an experimental measurement of the natural frequencies of free vibration. Optimal estimates for the elastic constants are obtained by minimizing the differences between these values. Two separate examples are considered in this study, with promising results.
