Mechanics of Wave Behavior in Explosively Loaded Rod

Abstract

High-speed photography has been used to observe and define the pattern of stresses generated by an explosive charge detonated on the end of a right circular cylinder. It was found that the internally convex cylindrical surface transforms and focuses the energy of the blow first in the form of a converging tensile wave which is followed shortly by a similarly converging shear wave. Damage is successively wrought by the two converging waves which arrive one after the other; the damage being due to the shear wave extending further down the cylinder. The diameter of the cylinder regulates the extent of the damage, limiting severe damage to the first three diameters of length. Within another diameter or so of length, the original dilatational wave is essentially transformed into a rod wave.
