Optical characterization of the dynamic mechanical response of advanced aerospace materials and structures
Abstract
The objective of this Defense University Research Instrumentation Program (DURIP) proposal is the development of an experimental facility for the full-field, optical characterization of the dynamic response of architected materials and structures across multiple scales. High speed photography, advanced motion capture, and digital image correlation (DIC) techniques will be employed for the multi-scale high-resolution characterization of events such as wave propagation and dynamic large deformations in novel metamaterials and metastructures. The motion capture system will be used to optically characterize the large deformations occurring at slower time scales while the concomitant wave propagation is captured through the use of high-speed photography and DIC. Applications include wave steering, stress wave mitigation, crashworthiness and development of novel structures. In particular, this research enables novel experimental techniques which through the purchase of: i) a motion capture system, and ii) a high-speed camera imaging array.
