Abstract

The collapse and formation process of quasi-spherical explosively formed projectile (EFP) was simulated by nonlinear dynamic software AUTODYN. Effects of structure parameters of liner outer curvature radius (R₂) and liner thickness (h) on the velocity and length/diameter ratio of EFP were studied. Results show that as the increasing of outer curvature radius and liner thickness, velocity and length/diameter ratio of EFP decrease. The relationship between outer curvature radius and liner thickness of the quasi-spherical EFP is obtained. X flash radiographs of EFP with structure parameters h=0.136D_k and R₂=0.76D_k are obtained. The results of numerical simulation are well agreement with X flash radiographs.
