Abstract
The charge of the invention comprises a plate placed between the explosive charge and the liner. The diameter of the plate is equal to the internal diameter of the casing of the charge. The material used for the plate must be such that its density is lower than or equal to that of the material used for the liner and must have a volumetric compressibility modulus greater than or equal to 100 GPa, with the thickness of the plate greater than or equal to that of the liner at any point of a central area surrounding the axis of the charge, so as to ensure that upon initiation of the charge the centripetal deformation of the plate will be less than that of the liner.
