ABSTRACT:
A sample of material is tested to determine its elastic properties by generating a stress wave from a first transducer and comparing the stress wave received by a second transducer positioned on the opposite side of the sample to the first transducer. The phase shift and attenuation are used to calculate the elastic properties of the material.
