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=0.136Dk and R2=0.76Dk are obtained. The results of numerical simulation are well agreement with X flash radiographs.
