Abstract
Keywords
On the basis of numerical simulation within a two-
dimensional axisymmetric problem of continuum mecha-
nics the study shows that transition from the constant thick-
ness of hemispherical shaped-charge liners to degressive
thickness (decreasing from top to the basis) makes it possible
to essentially increase the velocity of the formed shaped-
charge jets due to conditions for implementing the implo-
sion principle (spherically symmetric convergence of liner
material to the center). Copper was considered as material of
liners. We compared parameters of shaped-charge jets from
hemispherical liners to parameters of the jet formed by the
modern typical shaped charge with copper conic liner which
provides penetration depth into a steel target at the level of
10 diameters of the charge. To carry out the comparative
analysis, we calculated mass and velocity distributions for
shaped-charge jets by results of numerical simulation. The
velocity of the jet’s head part and its full mass acted as inte-
grated indicators for comparative estimation of the shaped-
charge jets limit length which defines the jets potential pene-
trability. Findings of the research show that use of hemi-
spherical liners of degressive thickness in shaped charges
makes it possible to form the shaped-charge jets whose head
part velocity and penetrability are not inferior to the one of
the jets formed by conic liners
