Abstract
This paper presents an analysis of the possibility of increasing the ultimate elongation and penetration capability of metallic shaped-charge jets in the presence of an axial magnetic field in the shaped-charge liner by the heating and thermal softening of the jet material due to a sharp increase in the magnetic-field induction in the jet formation region upon liner collapse. This process is studied by numerical simulation in a quasi-two-dimensional formulation taking into account the inertial extension of the conductive rigid-plastic rod in the presence of a longitudinal magnetic field in it.
