There exists a great need for armor systems with greater mass efficiencies and bal-
listic limits. This thesis explores the development of a new field of armor capable of sat-
isfying the increased demand for modern armor: Mechanically Reactive Armor or MRA.

ergy. After identifying these principles, the specific mechanical functions required by the
principles are isolated. These functions represent the physical behavior and capabilities of
real mechanisms that satisfy the specific design principles. Using these mechanical func-
tions and other benchmark concepts as a guide, established concept generation methodol-
