Abstract Scope |
Additively manufactured (AM) metal-metal composites consisting of PrintCasted 316L austenitic stainless-steel lattice structures infiltrated with A356 casting alloy, have recently been developed for use in high energy absorption systems. The ability to intricately form the composite and control the phase distribution give engineers a greater latitude over material property design with proposed applications ranging from static load bearing to dynamic blast containment structures. In this work, new lattice structures are examined within finite element models in order to determine optimized structures for use in energy absorption systems. 316L austenitic stainless-steel lattice structures taking on face center cubic and diamond cubic structures are examined with varying volume fractions (20-60% by volume; the deficit being A356 casting alloy). Particular attention is given to the analysis of localized/non-localized damage initiation and propagation and the role this plays in energy absorption systems. |
