Talk : Uncovering the mechanics of architected materials in dynamic conditions

Architected materials across length scales—from nanometers to centimeters—have demonstrated unique mechanical properties enabled by a variety of 3D material morphologies. Significant advances in our understanding of these materials have pointed to structure-property relations that lead to unique macroscopic mechanical properties. Despite this progress, our knowledge of these materials is primarily limited to quasi-static deformation, while their dynamic properties remain to be fully understood. In this talk, we present explorations on the dynamic response of nano- and micro-architected materials under extreme dynamic conditions, presenting novel non-contact and impact characterization techniques to determine acoustic and energy absorption properties. Specifically, we will discuss high-throughput dynamic elastic-property characterization and supersonic microparticle impact testing on periodic architected materials at the nano- and microscale.
