Abstract:

An experimental program was conducted to establish the sensitivity of cased charges of Composition B, in the molten and solid state, to impact by high velocity steel fragments. Primary fragments having a square cross-sectional area and weighing 0.5, 1.0 and 2.0 ounces were propelled at targets by explosive means. Velocity levels were varied between 3,000 and 7,000 fps in order to determine the threshold velocity range required for a detonation. Results of this program indicate that molten Composition B charges are significantly more sensitive to impact than solid charges. In addition, it appears that a relationship exists between the kinetic energy of the fragment, its impact area and the threshold detonation velocity. Author
