Abstract

In order to obtain explosion energy dispersion rules of confined asymmetric structure, experiments of a D-shape warhead in center initiation mode and off-center initiation mode on end faces were conducted to analyze fragment projection angles.The fragment ejection process of five different structures at different initiation modes were simulated by using the finite element software LS-DYNA.The study result shows that:as for the D-shape warhead, off-center initiation at both ends is the best initiation mode; Better damage effect can be achieved by controlling length of deformed arc intervenient between third and quarter of circumference.

Key words： explosion mechanics; asymmetric structure; premade fragment; energy distribution; end face
