| Abstract: | A reliable experimental technique designed to study impulse-wave propagation in materials is described. This technique uses a mechanical shaker to subject vertically mounted cylindrical specimens to impulsive forces. The method is applicable to the study of impulse-wave propagation in cylindrical specimens when the length of the pulse is great compared to the diameter of the specimen, and the material is not stressed beyond its proportional elastic limit. The procedure is particularly suited for biomechanical measurements in which the specimen is to be subjected to repeated impulsive loading. Shockabsorption capacity of bone joints can be studied with this setup. The apparatus can also be used for modal analysis. |
