主讲人简介：Qing Peng is a postdoctoral research associate in Department of Mechanical, Aerospace & Nuclear Engineering, Rensselaer Polytechnic Institute. He received his Ph.D. in physics from University of Connecticut in 2005, M.S. from Binghamton University, and B.S. from Peking University. His research focuses on advanced materials mechanics using multiscale and first-principles computational modeling and simulation. He is the main inventor of the QCDFT (Quasi-Continuum Density Functional Theory) method which allows full quantum simulation of materials at micron scales and beyond. With QCDFT, he and coworkers have successfully unveiled the strengthening mechanism of solid solution and hydrogen assisted cracking in aluminum. He also studied the nonlinear mechanical behaviors of two-dimensional materials, providing a safe-guide of their applications. In addition, he studied the mechanics coupling with radiation hardness in 2D materials, radiation damage in HCP metals, and pyroelectrics.
