The Young Investigator Award (YIP) is open to scientists and engineers at research institutions across the United States who received Ph.D. or equivalent degrees in the last five years and who show exceptional ability and promise for conducting basic research.The objective of this program is to foster creative basic research in science and engineering, enhance early career development of outstanding young investigators, and increase opportunities for the young investigators to recognize the Air Force mission and the related challenges in science and engineering.

This YIP proposal is designed to make predictions of high-strain rate responses more reliable, robust and accurate by (1) deriving, formulating and verifying a dynamic multiscale discrete-continuum model that does not require macroscopic phenomenological laws to drive simulations, and (2) utilizing 3D printing techniques to make validation exercise fully replicable by third parties. One innovative aspect of the proposed research is the development of the open-source codes and validation exercises that utilizes 3D printing techniques to manufacture replicable specimen. This newfound transparency offered by 3D printing technique will provide the key to encourage other researchers to investigate, replicate and discover and make comparisons without injecting bias. As an example, split-Hopkinson bar tests conducted with digital image correlation on the natural and manufactured particle assemblies will significantly reduce the experimental uncertainties and provide valuable insights and quantifiable data to assess the accuracy and robustness of the multi-scale model.
