Kinetic energy of an inert projectile or its fragment can cause considerable damage to soft tissues and cause debilitating injuries or fatalities. The primary aim of threat mitigation due to kinetic energy dissipation is to provide adequate protection against projectiles or fragments in the form of body shields. Recently, novel nanocomposite materials reinforced with nanotubes are used as shields to protect the soft-tissues during impact. Soft tissues constitute an important part of human body performing various mechanical functions and a deep understanding of the behavior of soft tissue is required to characterize its response to external mechanical forces. Soft tissues are non-homogenous anisotropic materials, and their properties are dependent on the the physiological structure. In this paper, a multiscale homogenization-based analysis of the constituent properties of soft tissues and underlying endoskeleton are developed for impact mitigation using nanotube-reinforced composite shields. © 2013 Springer Science+Business Media Dordrecht.
