    Abstract
  • In order to study the influences of liner curvature radius on the formation of double layer shaped charge liner (DLSCL) into tandem explosively formed projectile (EFP), the numerical simulations on the mechanical phenomenon of DLSCL forming into tandem EFP were carried out by using two-dimensional finite element dynamic code AUTODYN. The formation mechanisms of DLSCL and the influence of curvature radius on the formation of DLSCL were studied. After tests on the formation of DLSCL were performed, the X-ray pictures were obtained. Comparisons between experimental results and numerical simulation results show a good agreement. It can be concluded from the results that DLSCL can form tandem EFP and the liner curvature radius has great influence on the velocity, shape and l/D radius of tandem EFP.
