A new mathematical model for the relation between stand-off and penetration of shaped charge jets

A new mathematical model describing the penetration capacity of a SC (Shaped Charge) jet is proposed. This model should be easier to use than the old models in computer programs for assessment of effects and vulnerability of complex targets caused by SC warheads, especially regarding the modelling of the effects of BAD (Behind Armour Debris) that is ejected from armour shields perforated by SC jets. Since the BAD modelling also requires a model for the diameter of the hole produced by the jet such a model is also proposed. Finally the manner in which the stand-off relation should be used to calculated penetration of several spaced target plates is described.
