A Postdoctoral Research Associate Position at the University of Wisconsin-Madison

A Postdoctoral Research Associate Position is available immediately in Professor R. Thevamaran’s laboratory (https://thevamaran.engr.wisc.edu) at the Department of Mechanical Engineering of the University of Wisconsin-Madison. The research will focus on design, fabrication, micro/nanostructural characterization, and thermo-mechanical testing, and modeling of carbon nanotube-based hierarchical composites.

Independent control of dynamic material properties by exploiting structural hierarchy and intrinsic structural gradients

Achieving high damping and stiffness is challenging in common materials because of their inter-dependent scaling. Controlling extreme mechanical waves requires synergistically enhanced damping and stiffness. We demonstrate superior damping and stiffness in vertically aligned carbon nanotube (VACNT) foams that are also independently controllable by exploiting their synthesis-tailored structural hierarchy and structural gradients. They exhibit frequency- and amplitude-dependent responses with dramatically tunable dynamic stiffness while maintaining constant damping.

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.

A few experimental studies on the dynamic behavior of foam-like aligned carbon nanotubes

I'm posting a few experimental studies we have conducted on the dynamic behavior of hierarchical fibrous materials, using vertically aligned carbon nanotubes as a model material. I hope these will be useful to those who are interested in buckle-instabilities, multiscale behavior, and energy absorption mechanisms.
