A Fragmentation Model for Cylindrical Warheads

Abstract

This report presents a descriptive model for the expansion and fragmentation behavior for the case of a single-point, end-initiated cylindrical warhead. This model divides the overall behavioral process of the warhead case into four distinct zones of behavior which occur between initial case motion and fragment impact. The report describes what is happening in each zone in terms of (1) the physical behavior of the warhead case and (2) the respective velocities of the metal case or fragments. This model is based on the results of numerous experimental studies using high speed photography and fragmentation test arenas. Several examples in the use of the model are presented based on these studies.
