Numerical simulation of the formation of shaped-charge jets from hemispherical liners of degressive thickness

Abstract: The formation of shaped-charge jets from hemispherical copper liners of degressive (decreasing from top to bottom) thickness is analyzed by numerical simulation of a two-dimensional axisymmetric problem of continuum mechanics. The basis for the comparison was taken to be the parameters of the jet formed from a modern standard shaped charge with a conical liner which provides penetration of a steel target to a depth equal to 10 charge diameters. In the comparative analysis, we used calculated mass-velocity distributions and the ultimate jet length-velocity distributions obtained on the their basis, from which the potential penetrability of jets was evaluated. It is shown that the use of hemispherical cumulative liners of degressive thickness makes it possible to form shaped-charge jets that are not inferior in head velocity and penetrability to the jets from conical liners.
Keywords: shaped charge, shaped-charge jet, hemispherical liner, degressive thickness, mass-velocity distribution, ultimate jet length-velocity distribution.
