Mechanics of materials is facing another golden age with the evolution of nano- and bio-technology. Although the fundamentals of mechanics and materials sciences still prevail, new phenomena at these scales pose challenges to our current understanding and require new treatment from the perspective of both modeling and experiments. For instance, at the nano- scale, surface effects become more dominant, and quantum (discrete) effects start to be pronounced. These phenomena likely involve not only mechanics, but also other disciplines such as electronics, thermodynamics and biophysics. We may note that multiscale modeling including atomistic simulation has seen remarkable success, while experimental work lags due to many challenges at the nanoscale. The fusion of applied mechanics, material sciences, and MEMS/NEMS technology now offers unprecedented opportunities for performing nanoscale experiments in a quantitative manner, leading towards further understanding of mechanics and mechanics-related issues at small scales. Our group is interested in experimental mechanics of micro/nano materials and biological cells, with emphasis on multiphysical characterization of nanostructures and device development based on their unique properties. We are interested in developing novel instruments and experimental techniques based on MEMS/NEMS devices. |
