Materials Science Engineering functionally graded materials ballistic armor binder jetting additive manufacturing directed energy deposition finite element analysis simulation Functionally graded materials (FGMs) show promise in solving a number of design challenges, but there are challenges associated with their fabrication. Advances in additive manufacturing (AM) have improved the ability to produce FGMs, creating more opportunities for their use. In this study, additive techniques were used to create four types of FGM system in order test their suitability as armor materials against small arms projectiles: M300/316L, bronze-infiltrated 420S/A356, PH17-4/A356, and Tethonite/A356. Two methods were used in the fabrication of these FGMs: directed energy deposition (DED) for the compositionally graded M300/316L system, and hybrid printing and casting method to create gyroid-based mesostructural FGMs for the remaining systems. These FGMs were subjected to ballistic testing and their performance, measured in depth of penetration, was compared to monolithic materials. Additionally, finite element analysis (FEA) of the ballistic protection of these FGMs was presented and compared to experimental results. Poor agreement was found between model and experiment for the compositionally graded M300/316L and mesostructural tethonite/A356 systems, highlighting the need for accurate material models, but the PH17-4/A356 model found good agreement with experimental outcome. Among the FGM systems tested, the PH17-4/A356 mesostructural system showed the most promise, being able to deflect the projectile as it passed though the plate. 2020-08-06 English text Youngstown State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ysu1596474811965998 http://rave.ohiolink.edu/etdc/view?acc_num=ysu1596474811965998 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
