Abstract
A composition B filled charge, with an Armco iron liner, point initiated was shot in order to recover the projectile. An identical charge, with the point initiation shifted from the axial position has been fired in the same conditions. Those two experiments were numerically modelized with the finite elements RADIOSS code, with a lagrangian formulation for the metallic elements and an Arbitrary Lagrange Euler formulation for detonation products. The rotational-symmetry charge was calculated with the 2D version of the code and the assymmetrical charge was calculated with the 3D version. Good agreement was obtained between the experiment and the calculation. This paper will present the experimental results and the numerical predictions. (EMI)
