Shaped Charge To The Formation Of The Simulation And Theoretical Study Of The Jet

In this paper, the basic theories and the state-of-the-art of research development of shaped charges over the world were introduced briefly first. Then, the background , objective and necessity of the research project for this dissertation were interpreted in details. With the collapse model of chou's and the modified PER theory, one dimension calculation was obtained to describe the process such as liner collapse, jet formation, jet stretch and penetration of different explosive filled structure by Matlab tool and good result was attained.At the same time , the inviscid compressible flow model were deduced .In addition, the critical condition of jet formation were discussed and some key factor were pointed out , after integrate comparison with different jet criterion , and the least prick angel were concluded about some familiar materials of liner . Therefore , any later study on the same issue or in the same field may find it helpful to go on research.
