Abstract: The performance of the respected Frank-Zook penetration algorithm (Zook, J. A., Frank, K., and Silsby, G. F., Terminal Ballistics Test and Analysis Guidelines for the Penetration Mechanics Branch', BRL-MR-3960, January 1992) is examined in light of an anticipated class of target technologies involving laminated targets whose layers are thin relative to the projectile diameter. This class of target designs encompasses multifunctional integral armors and, in the limiting case, armors incorporating functionally-graded materials. Such armor classes represent potential candidates for the Army's Future Combat System. The ability to effectively model the ballistic response of advanced armors is paramount to accurately assessing system lethality and vulnerability for future weapon systems and platforms
