This paper reports the quantitative measurement of a full spectrum of mechanical properties of fivefold twinned silver (Ag) nanowires (NWs), including Young’s modulus, yield strength, and ultimate tensile strength. In-situ tensile testing of Ag NWs with diameters between 34 and 130 nm was carried out inside a scanning electron microscope (SEM). Young’s modulus, yield strength, and ultimate tensile strength all increased as the NW diameter decreased.
We systematically investigated the interesting electric response of the aligned CNT ribbons under mechanical strain. We found that CNTs slide on a PDMS substrate under tension, but buckle under compression (releasing). Such an irreversible mechanical deformation is responsible for the observed irreversibility in the electric resistance upon the first stretching/releasing.
A postdoctoral position is available in the Computational Mechanics and Materials
Group within the School of Civil and Environmental Engineering at Cornell
University (http://ceeserver.cee.cornell.edu/dhw52/index.shtml).
The project will involve the application of ab-initio atomistic modeling
techniques to illuminate the mechanisms by which impurities and environment
influence the mechanical failure of engineering materials.
I was looking for some decent presentations on Rare Metals, and was at a loss in finding some. It would be great if anyone could direct me to anything related to rare metals, especially on presentation form. My email is rummantdm [at] yahoo.com.

Dear Members,
I am very new to field of nanoindentation and my question might appear too simple.
I am indenting an elastic - plastic material (polymer blend) with spherical indenter. I am well verse with hertz contact mechancis theory and indentation theories like Oliver & Pharr, JKR, DMT and few others.
Sponsored by the National Science Foundation and the NSF Institute for Mathematics and its Applications, the University of Minnesota (Minneapolis, Minnesota, USA) is hosting a workshop on the boundary element method (BEM) April 23-26, 2012. This workshop consists of a two-day short course and a two-day colloquium on advances in the BEM with educational and industrial applications. Researchers and engineers from around the world, as well as students (both graduate and undergraduate) are invited to participate in this workshop.
Novacam 3D Profilometer Software
The Novacam three dimensional software programs are used with all Novacam Profliometers. The program permits the consumer to define how big the region, or line to be measured, along with the lateral resolution from the measurement.
Novacam's high end Data Acquisition Profilometer Software programs are incorporated with all of MicroCam non-contact profilometers.
