HIGH-VELOCITY PENETRATION INTO A METAL BARRIER BY A VISCOELASTIC ROD

A model has been proposed for a high-velocity interaction of a viscoelastic rod with a barrier resulting in ejecting a plug in a target. We have obtained an approximate analytical solution of a problem, in which the deformation of the striker and the target is considered jointly, and a relation that associates the barrier penetration time with the plug mass, the critical shear strength of the target, and the striker parameters in the case when the plug after-penetration velocity is equal to zero
