Abstract

Abstract: Initiation methods affect the formation and morphology of multiple directional fragments (MDF) warhead greatly. Based on the explosively forming mechanism, the effect of annular initiation radius on the fragment formation is analyzed by simulating the process of the liner from the incisory cover to fragments. The results show it the annular initiation radius is bigger, the MDF tip fragments increase quickly but the residual mass decrease gradually; the radial dispersion angle increases firstly and then decreases; for a certain MDF warhead, if the annular initiation radius is between 8 mm and 12 mm, the fragments penetration and damage effect are the best.

Key words: mechanics of explosion, multiple directional fragment, detonation wave, annular initiation radius, multiple directional fragments warhead parameter
