Lab of Solid and Structure Mechanics

Yuanli Bai is a Professor of Mechanical Engineering at UCF. He obtained his Ph.D. degree in mechanical engineering from the Massachusetts Institute of Technology (MIT) in 2008. He obtained his bachelor’s and master’s degrees from the Department of Automotive Engineering from Tsinghua University in 2000 and 2003, respectively. While at MIT, he worked under the supervision of Professor Tomasz Wierzbicki, the director of Impact and Crashworthiness Lab, on plasticity and ductile fracture mechanics of materials. Prior to joining UCF in 2011, he was a mechanical engineer at General Electric Global Research Center in Niskayuna, New York.

Dr. Bai’s current research is focused on plasticity, fracture and fatigue testing, modeling and simulation for various engineering materials, including lightweight alloys, metallic matrix nano composites, polymer matrix composites, soft tissue materials, and recently virus/proteins. He operates the Lab of Solid and Structure Mechanics under the MAE department. Dr. Bai has published over 100 papers in the field’s most highly rated journals and conference proceedings.
