| Abstract Scope |
Our desire for tunability of structural mechanical response informs our choice of lattice structures (or metamaterials) and an elucidation of their response to static and dynamic loads. However, these scenarios are typically in opposition: static loads must be supported sufficiently far away from the onset of buckling or yielding, whereas dynamic loads are typically ameliorated by crushing of the lattice, which provides excellent energy-absorption due to the large plastic deformation accompanying densification. Moreover, emergent behavior, such as material jetting and elastic wave propagation, arising from the open architecture has been observed in situ under dynamic loading conditions. In this work we will outline a design scheme for lattice structures that must simultaneously support static loads while enduring high amplitude impulsive loads, all without compromising structural integrity. The design rules developed in this study expand the domain of applicability of lattice structures to challenging dual-loading regimes spanning decades of strain rates. |
