Abstract
A method for forming a fragmentation explosive munition includes providing a casing, and forming holes in the casing using electrical discharge machining (EDM), thereby forming a modified casing.
Claims19
A method for forming a fragmentation explosive munition, the method comprising:
- providing a casing;
- and
- forming microholes in the casing using electrical discharge machining (EDM), thereby forming a modified casing;
- wherein each of the microholes provides an initiation site in the modified casing for fracture of the modified casing as the modified casing expands under explosive loading;
- wherein the microholes each have a length to diameter ratio of at least 50 to 1;
- and
- wherein an elastic modulus, a yield strength, and an ultimate strength of the casing remain substantially unaffected by the microholes.
