A shaped charge is an explosive charge shaped to focus the effect of the explosive's energy. . This temperature is consistent with a hydrodynamic calculation that . The penetration depth is proportional to the maximum length of the jet, which is For optimal penetration, a high explosive with a high detonation velocity and.
