Perforation of multi-layered metallic targets by kinetic penetrators
Апстракт
In the paper it is considered problem of perforation of multi-layered metallic targets by deformable cylindrical flat-ended penetrators. Analytical model for perforation of multilayered targets is created on the basis of complex, multiphase, phenomenological model of deformation waves. Two variants of model involve cases of spaced and jointed layers of target. Computer program based on developed model enables determination of residual penetrator’s velocity as well as ballistic limit velocity. Double-layered target with constant total thickness is specially investigated in order to define optimal ratio of layers’ thickness that provides maximum target resistance. Results of analytical model are in good correspondence to experimental data. These results also enable formulation of few conclusions that can have practical importance.
