Abstract
The sensitivity of predictions of self-forging fragment shape and kinetic energy to variations in the Jones-Wilkins-Lee (JWL) equation of state for the detonation products is studied parametrically using the EPIC-2 finite element computer code. JWL parameters are varied for two warhead designs: the OXROD (EXplosive Remote Opening Device) and the REDM (REsearch and Development Munition). The resulting percentage changes in shape factor and kinetic energy are presented in tabular and graphical form, and the most influential JWL parameters are identifiedl.
