Postdoctoral Research Associate Position at the University of Wisconsin-Madison, Madison, WI.

A Postdoctoral Research Associate Position is available in Professor R. Thevamaran's laboratory at the Department of Engineering Physics to study the dynamic behavior and properties of nanostructured metals and hierarchical materials. A strong background in experimental solid mechanics and materials science is required for this research.

Effects of grain size and microstructure rigid rotations on the bending behavior of nanocrystalline material beams

Due to the intensive decrease in grain sizes of nanocrystalline materials (NcMs), a large volume fraction of atoms reside in the interface regions between crystals forming an atom-cloud phase with a distinct atomic structure. Moreover, the surface to volume ratio of the grain increases, thus its surface energy will significantly affect the mechanical properties of NcMs.

Mechanics of Crystalline Nanostructures Symposium at 49th SES Meeting (Abstract Deadline: April 2, 2012)

Dear Colleagues,

 

We would like to bring your attention to the Mechanics of Crystalline Nanostructures Symposium at the 49th Society of Engineering Science (SES) Meeting at Georgia Tech on October 10-12, 2012.

TEM image showing uniformly distributed nano-fibers inside epoxy matrix

We observed that all nanofibers are curved not straight. So the Young’s modulus of the nanocomposite material is always lower than the model prediction using traditional micro-mechanics theory assuming straight nanofibers/nanotubes, as reported by Prof. Y. Huang’s group at UIUC.
