Abstract:

The objective of this DURIP was to develop an experimental facility for the full-field, optical characterization of the dynamic response of architected materials and structures across the scales. Two main experimental techniques were proposed using i high-speed photography and ii advanced motion capture to resolve the multi-scale high-resolution characterization of events such as wave propagation and dynamic large deformations in novel metastructures. The development of the experimental facility was successfully completed in mid-May 2019 and is currently being used for the aforementioned objectives with an initial focus of investigating the impact performance of tensegrity lattices.
