Numerical Study on Double Layers Fragment Warhead under Asymmetrical Initiation Zaicheng Wang1,a, Chunlan Jiang 2,b, Zhiyuan Chang 3,c 1,2,3State Key Laboratory of Explosion Science and Technology, Beijing Institute of Technology, Beijing, 100081,China awangskyshark@bit.edu.cn, bjiangchunwh@bit.edu.cn, cwshark9@163.com Keywords: Directional warhead, Asymmetrical Initiation, Double layers fragments, Numerical simulation Abstract: Increasing the velocity and distributing density of fragments through asymmetrical initiation is an efficient way to improve the damage capacity of warheads.
PLASTIC_KINEMATIC material model was used for tungsten alloy fragment; HIGH_EXPLOSIVE_BURN model was used for explosive material and JWL was adopted as equation of state[5]. 3 Results and Analysis of Numerical Simulation The numerical simulation of single layer fragments under symmetrical initiation and double layers fragments of the warhead under asymmetrical initiation are shown in Fig. 2 and Fig. 3.

The experiment was carried out by means of a Scanning Electron Microscopy (Lecia Steroscan 440) and a material tester system in order to observe the change on the surface of the fibers when the specimen was extended.
The load and displacement were recorded by a mini material tester system during the tensile process.
