Abstract


In this paper the combined numerical-experimental approach was used to investigate the explosively driven fragmentation of warhead casing . The experimental tests were conducted with the aim of gathering the data which will be useful for verification of the subsequent simulations. During the experiments after the detonation of explosive, the fragments of the ruptured casings were collected. The number and the mass distribution of fragments were examined. Then, the numerical simulations were conducted with the same explosive fragmentation geometry as in experiments. The correctness of the conducted simulations and the applicability of the used numerical technique were verified by comparing the numerical results, especially fragments number and their mass distribution, with the conducted experimental tests outcomes. The reasonable agreement between examined parameters was achieved, what testifies that the technique can be used in the future to predict the fragmentation behavior of warheads casings.
