Abstract

In order to build a model to predict the initial velocity of explosively-driven cubical fragments, the simulation is carried out to analyze the explosive driving process by using AUTODYN hydrocode. The explosive driving process is divided into two stages, i. e., leakage and non-leakage of detonation product. A model of cubical fragment velocity is established by theoretical derivation based on a series of hypothesis, impulse theorem and modified gas pressure formula. The results are well consistent with the experiment results. The results show that the number and deformation of fragments have influence on the initial velocity of fragment.
