ABSTRACT |
In this talk, I will present an overview of the research in our group on the manufacturing of multifunctional materials in metallic and polymeric forms. In metallic materials, I will show how understanding the mechanics and microstructures resulting from severe shear deformation processes is useful for predicting dynamic mechanical behavior and controlling product outcomes in an array of manufacturing applications. The utilization of shear strains ranging from ~1-10 and strain rates ~10-103/s for the creation of novel ultrafine grained and nanostructures will be demonstrated. The utilization of the resulting nanostructured bulk forms in multifunctional applications ranging from the fabrication of radiation damage-tolerant materials, structural and biomedical components will be examined The second half of the talk will demonstrate our research on polymeric materials that can directly transduce photonic energy into mechanical work. The utilization of azobenzene-functionalized polyimides and liquid crystal polymer networks for such transduction will be demonstrated. Novel approaches for accelerating the photomechanics and their utilization in transformative photomechanical machines will be presented.

BIOGRAPHY
| Ravi Shankar is currently an Associate Professor in the Department of Industrial Engineering at the University of Pittsburgh. Prior to this, between 2006 –2012 he was an Assistant Professor. He obtained his Ph.D. in 2006 from Purdue University in Industrial Engineering. His research has focused on problems in mechanics of severe shear, deformation of small volumes, stability of nanostructured materials and manufacturing. He was a winner of the Society of Manufacturing Engineers’ 2010 Outstanding Young Manufacturing Engineer Award and is a William Kepler Whiteford Endowment Faculty Fellow at the University of Pittsburgh. He has authored about 40 journal articles, some of them in fact, quite readable.
