The subject of adiabatic shear banding is quite classical and the main assumption is that it consists of  structural/mechanical instability in which the thermal softening effects play a dominant role in the generation of the band (Zener-Hollomon).

I would like to focus on the phase that precedes global failure, namely up to the peak stress or strain) at which the material starts to exhibit negative strain hardening.

Job Description: The CINT Science Department is searching for a postdoctoral appointee to pursue research in the area of leading-edge electron microscopy of nanomaterials and their properties. The successful candidate will work closely with the staff scientist heading electron microscopy research activities at CINT on topics related to the structural, mechanical, thermal, and electrical properties of modern nanomaterials.

Browsing through past themes, I realize that this is the third time the topic of experimental mechanics at the nanoscale has been highlighted in the jClub forum. There are many problems that require experimental research at the nanoscale that we can do this a few more times without being repetitive. I would like to focus this discussion on the fundamental issue of friction.

The Department of Civil and Environmental Engineering at the University of Pittsburgh invites applications for a faculty position effective September 1, 2009. The search is open to all ranks depending on qualifications and experience.
