Abstract
A fragmentation body comprising a substantially monolithic structure comprising a metal material and comprising a major surface having an indentation pattern therein, and an opposing major surface having an opposing indentation pattern therein, the opposing indentation pattern being substantially aligned with the indentation pattern. A warhead and an article of ordnance are also described.
Claims20
A method of forming a fragmentation body, comprising:
- forming a metal material comprising at least one high-density metal and at least one metal having a lower melting point than the at least one high-density metal;
- forming the metal material into a substantially monolithic structure comprising a major surface and an opposing major surface, the major surface exhibiting an indentation pattern and the opposing major surface exhibiting an opposing indentation pattern substantially aligned with the indentation pattern.
A method of forming a warhead, comprising:
- providing a substantially monolithic fragmentation body comprising a high-density metal and a metal having a lower melting point than the high-density metal proximate an explosive charge within a containment vessel, the substantially monolithic fragmentation body having:
- a major surface exhibiting an indentation pattern;
- and
- an opposing major surface exhibiting an opposing indentation pattern substantially aligned with the indentation pattern.

A method of forming an article of ordnance, comprising:
- coupling a warhead to first end of a rocket motor assembly, the warhead comprising:
- an explosive charge;
- and
- at least one substantially monolithic fragmentation body proximate the explosive charge and comprising at least one high-density metal and at least one metal having a lower melting point than the at least one high-density metal, the substantially monolithic fragmentation body having:
- a major surface exhibiting an indentation pattern;
- and
- an opposing major surface exhibiting an opposing indentation pattern substantially aligned with the indentation pattern;
- and
- coupling a tail section to a second, opposing end of the rocket motor assembly.
