Fragmentation of Ring Type Cylindrical Shell Made of Various Metals
Abstract
To study the fragmentation characteristics of shell made of various metals, a series of ring-type cylindrical shell, made of various metals, having widely different densities and physical properties, were statically fragmented. The resulting data ere analyzed in conjunction with a theory governing the sixes of fragments. The following conclusions were reached: (1) A direct variation appears to exist between the mean fragment mass and the maximum fragment mass when different materials are compared. (2) The mean fragment mass is partially dependent upon the following metallurgical properties of the shell: (a). The density of the metal. (b) The tensile strength of the metal. (c) The static reduction of area of the metal. Further, semi-empirical relations were obtained by which mean fragment mass could be predicted with some statistical accuracy from the preceding quantities, the geometry, and from the initial fragment velocity,V sub zero. Although the experiments all involved explosive RDX composition C3, there are theoretical reasons for expecting the same relations to hold for other explosives, whose identity may influence the mean fragment mass only through V sub zero.
