Abstract

In this communication we elucidate how topology affects the supercritical dynamic behavior of lightweight architected materials and in particular their Hugoniot stresses. We identify two topologies with distinct morphological characteristics but equal density and quasi-static strength. A series of dynamic simulations reveals that even though the stress histories for the two architected materials can vary substantially in terms of smoothness, or lack thereof, the corresponding extracted Hugoniot curves are indistinguishable.
