Yongming Liu, an assistant professor of civil and environmental engineering at Clarkson University, has received a $360,000 grant from through the U.S. Air Force Young Investigator Research Program (YIP).
According to Air Force Office of Scientific Research (AFOSR) officials, competition for the YIP award is intense. It awarded about $16.5 million in grants to only 43 of the 242 scientists and engineers who submitted research proposals in aerospace, chemical and material sciences; physics and electronics; and mathematics, information and life sciences.
Liu hopes that his project's outcome will greatly enhance the safety of next aircraft. His observations will assist in the development of a new, alternative and systematic approach for real-time fatigue reliability assessment of aircraft structures under different scenarios.
He proposes an innovative method to find metal fuselage fatigue in a much finer detail. Crack growth will be observed at a nanometer scale in place using scanning electron microscopy. Advanced imaging analysis will be used to investigate how the fatigue crack initiates and propagates.
Liu received his B.S. and M.S. in structural engineering from Tongji University in Shanghai, and his Ph.D. in civil and environmental engineering from Vanderbilt University in Nashville.
His research interests include fatigue and fracture of engineering materials and structures, probabilistic computational mechanics, risk assessment and management, multi-physics damage modeling and structural durability, multi-scale uncertainty quantification and propagation, structural dynamics and earthquake engineering, and stochastic finite element methods.
The 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 show exceptional ability and promise for conducting basic research.
Its objective 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.
