Based on the analysis of the kinematics and dynamics of the interaction between long
rods and moving in the same direction plates and considering the known experimental
data the authors revealed the following interaction modes: 1) the absence of interaction,
2) "slip" type interaction, 3) interaction with weak destruction of the rod and 4) interac-
tion with strong destruction of the rod. Using the Alexeesky – Tate model of penetration
of the rods into targets, analytical criteria for these modes was formed. To test these cri-
teria, the authors used ANSYS Autodyn software for 3D numerical simulation of the in-
teraction between the rods of high-density materials and moving steel plates, that, main-
ly, confirmed analytical criteria.
Keywords:
penetration into firm targets, reactive armor, high-speed interaction, numeri-
cal simulations.
