The Influence of Transient Flexural Waves on Dynamic Strains in Gun Tubes

Abstract

Transient waves or vibrations can be excited in several ways as ballistic pressure transverses the length of a gun tube. This report shows that despite their diversity, these transients will constructively interfere with the steady-state deformation in a highly predictable way to cause alternating regions of high circumferential strain along the tube. The method of stationary phase plays a key role in the analysis. Wave propagation; Gun barrels; Transient vibrations, Steady-state vibrations; Flexural vibrations; Cylinders. (jes)
