Abstract
Summary The purpose of this investigation is to study the effect of offset on the performance of segmented penetrators. The Eulerian wave propagation code CTH is used for this purpose. The veracity of the code in predicting the penetration depth of short L/D projectiles where channel sidewall interference is present is examined by comparing to a few experiments involving penetration of tungsten alloy cylinders into pre-configured cavities in monolithic armor steel. Having established the validity of the code in predicting this behavior, a series of calculations using four and eight L/D = 1 tungsten alloy segment trains at varying degrees of offset is performed, impacting semi-infinite armor steel targets. It is demonstrated that the alignment of the segments can have a considerable impact on the performance of the penetrator.
