Dynamic Strains in a 60-mm Gun Tube - An Experimental Study
Abstract
An exceptionally thin-walled gun tube was constructed to assess the applicability of steady-state deformations predicted by critical velocity theory. Strains created by internal pressure moving at subcritical, critical, and supercritical velocities were measured. Excellent agreement with steady- state predictions was observed throughout the entire subcritical regime. When the velocity of the moving pressure was only slightly greater than the critical value, a transitional state was noted. At higher velocities, the development of a trailing wave was observed and was found to be consistent with the theory. The existence of the predicted head wave was never actually observed. However, its presence was indicated in a frequency analysis of the data. Dynamics, Strains, Gun Tubes, Steady-State, Critical Velocity, Waves.
