Abstract:

The velocity of longitudinal and transverse acoustical disturbances were measured for a number of cast explosive compositions in bar form by the disturbance resonance technique. Youngs modulus, E, and the shear modulus, G, for the explosives have been derived from these measurements. The range in observations for these sound velocity measurements was on the order of 2 to 3. The sound velocities are estimated reproducible to 1 to 2 the computed moduli are therefore reproducible to 2 to 4. It is observed, however, that results of this type are highly dependent upon the state and conditions of preparation of the particular charges used in the measurements. Corrections to apply to the results are discussed. The results for TNT are compared to those of other investigators.
