Pagination or Media Count:
A controlled fragmentation explosive device is disclosed. Fragmentation control is achieved by providing both the inner and outer surfaces of a cylindrical case with intersecting longitudinal and circumferential v grooves having specific depth relationships. The inner and outer grooves are aligned with each other. The outer grooves are filled with a material for improving the acoustic impedance mismatch between the case and the volume within the v groove.
