Abstract
Numerical simulation studies of shaped charges with hemispherical liners of degressive thickness (decreasing from the top to the bottom) have been continued. The possibility of increasing not only the velocity but also the mass of the head sections of the formed shaped-charge jets to the level provided by conical liners of progressive thickness has been analyzed. For this purpose, liners of degressive thickness in the form of a truncated sphere and a semi-ellipsoid slightly elongated along the charge axis have been additionally studied.
