Abstract: For special requirements of penetrating multi-layer steel target,a design of explosively formed projectile(EFP)and its experimental study have been carried out.A compressed EFP assembly with a 60mm diameter of liner has been designed using the curved variable thickness liner design. The shape and velocity of the EFP when penetrating through the multi-layer steel target were measured with X-ray photography.According to the experimental results,the EFP shows the characteristics of moderate speed,good compactness and small length-radius ratio.In the process of penetrating multilayer steel target,the EFP has stable performance,and smash phenomenon does not exist.The experimental results show that it can penetrate through the six-layer steel target with thickness of 6mm and spacing of 2m.
