Applications are invited for an OCE Postdoctoral Fellowship in the research area "Local Property Enhancement in Light Alloys". The appoitment, for a period of three years. will be with the Light Metals Flagship and CSIRO Division of Materials Science and Engineering.

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. 

Abstract – A data analysis procedure has been developed to estimate the contact area in an elasto-plastic indentation of a thin film bonded to a substrate. The procedure can be used to derive the elastic modulus and hardness of the film from the indentation load, displacement, and contact stiffness data at indentation depths that are a significant fraction of the film thickness. The analysis is based on Yu’s elastic solution for the contact of a rigid conical punch on a layered half-space and uses an approach similar to the Oliver-Pharr method for bulk materials.
