Physics hypercumulation and comdined shaped charges

The novel points of view to the formation of shaped charge jets are described. The physics of so-called hypercumulation are described in details and confirmed by numerical simulations. It has been shown that hypercumulation effects allow to increase both the speed and mass of a cumulative jets much more than the theory by Lavrentyev-Birkhoff predict. The applications of novel effects are the oil-well perforations.
