摘要
Abstract
It is a new method to produce an explosively formed projectile (EFP) with fins by attaching aluminum cover on the liner.Experimental and numerical research were performed using this new method.Furthermore,the mechanism of forming fins was discussed.The new method of forming EFP with fins was simulated by LS-DYNA,and a contrastive analysis was carried out on three typical liners,including big-cone shaped,imperfect-sphere shaped and arc-cone shaped.The results from 3D numerical simulations and experiments were also analysed.Comparison of results show that three kind of liners could form obvious fins by this new method,and the results of numerical simulations are in agreement with the experiment data.The research provides a new reference method for designing EFP with fins.关键词
