Our research interests are focusing on Interface Engineering: Improve Mechanical Properties and Irradiation Tolerance of Materials by Tailoring Interfaces in Solids.
This is realized from two aspects:
- Discover unusual mechanical behavior (e.g., high strength and good ductility) of nanostructured composites and Develop theory and fundamental understanding of unusual mechanical behavior.
- Transform fundamental understanding of structural characters and deformation physics of nanostructured composites into a mesoscale capability of discovering, predicting, and designing superior nanostructured materials (strength, ductility, toughness, and radiation).
This is a multiscale effort involving synthesis, characterization, measurement, theory and modeling at different scales to design materials with desired properties. Theory and modeling at atomic scale employ Density function theory, Molecular Dynamics methods, Crystallography and Defect theory while experiments at atomic scale use transmission electron transmission microscopy to perform in situ/ex situ characterization and measurement. Theory and modeling at micro/meso/macro scales are focusing on developing physics-based predictive materials modeling tools (Interface Dislocation Dynamics and Crystal Plasticity theory that incorporate interface physics), while experiments at micro/meso/macro scales use SEM, TEM and EBSD etc. to observe and identify deformation mechanisms and texture evolution of nanostructured materials.
Wang spent the previous nine years at Los Alamos National Laboratory, with experience as a scientist and postdoctoral researcher. His research interests include multi-scale materials modeling, interface mechanics and engineering, fabrication and mechanics of nanostructured materials and nucleation, evolution and the role of defects in solids. Wang received a Ph.D. in mechanical engineering from Rensselaer Polytechnic Institute and both a master’s in solid mechanics and bachelor’s in engineering mechanics from Jiaotong University in China.
