Munitions structures comprising one or more high strength reactive alloys, in particular reactive bulk metallic glasses, have significant amounts of inherent chemical energy. This energy may be discharged by subjection of the munitions structure to rapid impulsive loading and fragmentation in the presence of oxygen and/or nitrogen. A munitions structure can be configured in both large and small penetrators, e.g. warheads and bullets, with increased lethality. The lethality of these munitions structures is augmented by means of rapidly and simultaneously imparting both mechanical energy (kinetic energy through impact and fragmentation) and chemical energy (blast and/or fireball) to a target. A high-strength reactive alloy can substitute at least in part one or both of explosives and inert structural materials in conventional munitions systems to improve performance and reduce parasitic weight of structural casing.

Methods and apparatus for artificial bird manufacturing in impact testing is described herein. An apparatus to generate an artificial bird for impact testing includes a mold generator to form a mold based on a bird class identification, a mold filler to fill the mold with a first layer of crushed ice and a second layer of crushed ice, a compressor to compress an ice surface of at least one of the first layer or the second layer of the crushed ice to form indentations on the ice surface, and a freezer to re-freeze the crushed ice layers inside the mold to form an artificial bird.
