QUASI-ONE-DIMENSIONAL LAGRANGE ANALYSIS AND ITS APPLICATION FOR SHOCK INITIATION IN CONDENSED EXPLOSIVES

Huan Shi(Dept, of Applied Physics, Changsha Insitute of Technology)Ding Jing(Dept of Engineering Mechanics, Beijing Institute of Technology)  
In this paper, a quasi - one - dimensional Lagrangian analysis method is presaent-ed. This method with the profiles of the pressure and the radial displacement at different Lagrangian positions, which determined from the two -dimensional (2-D) Lagrangian experimental technique for the input, can be used to solve the flow field near the axis of a 2- D shock initiation process. As a preliminary application, we show the analysing results of 2- D shock initiation process in pressed TNT at two loading conditions.
