摘要：
The normal incidence of shaped charge jets on confined explosive sheets is investigated through a series of 2D numerical simulations with the Eulerian code PISCES 2DELK. The basic mechanisms of the interaction are explored using a relatively simple criterion for the sheet efficiency to disrupt the jet, which is based on the undisturbed length of the emerging jet. The simulations are compared with experimental results published several years ago and the agreement is good. Using these simulations we show how one can optimize the efficiency of this interaction by using non-symmetrical confinement plates and stronger explosive sheets. (C) 1999 Elsevier Science Ltd.
