This paper describes a novel measuring system of elastic constants using a three-dimensional resonance method which can determine the elastic constants of several materials including ceramics and metals with elastic anisotropy. The system is composed of three modules: (1) measurement of resonant frequencies of cylindrical or rectangular parallelepiped small specimens, (2) numerical calculation of the specimen's resonant frequency, (3) control of these two modules and determination of the elastic constants. These modules are linked with feed back connections. To identify the vibration modes between measured and calculated resonant frequencies, a graphical user interface and a visualization tool for examining the vibration mode of the specimen were developed. Using this system, the turn-around time of determination of the elastic constants was much improved.
