Abstract Scope |
Additively Manufactured Interpenetrating Composites (AMIPCs) are metal-metal chain composite in development for use in high energy absorption systems. The reinforcing phase is comprised of 316L austenitic stainless-steel that is additively manufactured in continuous lattice configurations while the matrix phase is comprised of A356 aluminum-silicon casting alloy which is cast into the reinforcing phase. Previous work has shown that AMIPCs have excellent spall resistance under hypervelocity impact conditions over monolithic equivalents of either material alone or in bi-layer form. In this work, Finite Element Analysis (FEA) is used to investigate the energy absorption mechanism of AMIPCs under hypervelocity impact conditions. Model performance is evaluated with respect to prior measurements and parametric studies are undertaken to further evaluate performance as a function of composite volume fraction, structure, and interface. The outcome provides insight into material design criteria and performance predictions for hybrid metallic material systems with exceptional dynamic damage tolerance. |
