BODY ARMOR STRUCTURE, METHOD AND PERFORMANCE

摘要

Body armor structure (10) including a unitary material body having strike (10a) and opposite faces (10b), and an internal structure disposed between these faces which progresses from shatter-prone to ductile. The methodology of the invention includes the steps of responding to a projectile impact first with a fragmentation energy-dissipating mechanism, and thereafter augmenting such responding with a ductile elastic yield mechanism. The methodology further includes the step of telegraphing the responding action through a brittle/ductile transition region in the structure of the invention to engage the ductile elastic yield mechanism.
