Abstract: In situ nanomechanics is an emerging field that investigates the mechanical properties and deformation mechanisms of nanostructured materials. The study of in situ nanomechanics is typically conducted by integrating the real-time mechanical testing inside an electron microscope and the mechanics modeling with atomic resolution. It provides a powerful approach to visualize the intrinsic nanomechanical behavior of materials - seeing is believing. Recent studies of in situ nanomechanics will be presented in this talk, including the electrode degradation in nanoscale lithium-ion batteries (Nature Nanotechnology, 7, 749, 2012), deformation-induced stacking fault tetrahedra in FCC nanocrystals (Nature Communications, 4, 2340, 2013),  fracture toughness of graphene (Nature Communications, 5, 3782, 2014), and twinning-dominated deformation in BCC nanowires (Nature Materials, 14, 594, 2015). The in situ nanomechanics studies provide new insights that cannot be offered by traditional mechanics studies. Ultimately, the in situ nanomechanics research aims to enable the design of nanostructured materials to realize their latent mechanical strength to the full. The research involves collaborations with Drs. Scott Mao, Jianyu Huang and Jun Lou.

Speaker Introduction: Ting Zhu is a professor and a Woodruff Faculty Fellow in the George W. Woodruff School of Mechanical Engineering at Georgia Institute of Technology. He also holds a joint appointment in the School of Materials Science and Engineering at Georgia Tech. He received his B.S. in Engineering Mechanics in 1995 and Ph.D. in Solid Mechanics in 1999 (advisor: Prof. Wei Yang) from Tsinghua University. Then he received his Ph.D. in Mechanical Engineering from Massachusetts Institute of Technology in 2004. He worked as a postdoctoral associate at Harvard University, before joining Georgia Tech in 2005. His research is focused on mechanics and materials modeling. He receives the Sia Nemat-Nasser Early Career Award from the American Society of Mechanical Engineers (ASME) in 2013 and the Young Investigator Medal from the Society of Engineering Science in 2014. Zhu is an ASME Fellow.
