The fragmentation of D-shaped casing filled with explosive under eccentric initiation

With the technical development of new warhead designs and improvised explosive device protection, irregular casing filled with explosive has been paid more attention recently. In this paper, we studied the fragmentation of a type of D-shaped casing, which is a common asymmetric casing in the field o...
