Abstract
A shaped charge liner is made by forming a pair of hollow conical sub-liners, without any uncontrolled residual tangential shear stress (e.g. by a deep drawing method) so that they mate together to form a single conical liner. One sub-liner is inserted in the other and then one pair of subliner ends are locked together. Thereafter, the sub-liners are counter-rotated about their attachment point and locked together at their other pair of ends to retain the counter-rotation. This counter rotation generates opposite residual tangential shear stresses in the two sub-liners which may or may not be equal to each other.
