Dr. Li obtained her BSc and MSc in the field of Mechanical Engineering. In 2002 she obtained her PhD at Beijing University of Aeronoutics and Astronautics with a focus on the development of a viscoplastic damage constitutive model to evaluate the fatigue/creep damage of crystal alloys. After that she worked at Tsinghua University for two years and then University of Manchester for four years as Research Associate. Since 2008, she joined the Minnesota Dental Research Center for Biomaterials and Biomechanics (MDRCBB), University of Minnesota.
Dr. Li has expertise in stress analysis and failure analysis using finite element analysis. She has strong background in structural mechanics, mechanics of materials, fracture mechanics, and damage mechanics. Her research areas include dental biomechanics, dental biomaterials, nuclear graphite, and industrial polymers.
Fracture modeling of brittle and ductile materials
