1. Strain hardening and softening in nanotwinned Cu:

Nanotwinned Cu foils with about 99% coherent twin boundaries (TBs) among all the boundaries were made. These coherent

TBs, with an average spacing of 25 nm, were engineered approximately parallel to foil surfaces. Low plane-strain deformation

enhances the hardness by refining microstructure and introducing dislocations. High plane-strain deformation results in crystallographic

lattice rotation and reaction between dislocations and coherent TBs, and induces incoherent TBs, thus twin coarsening and

Dear Colleague: You are cordially invited to participate in the Nanobrücken 2014 Nanomechanical Testing Workshop, which will take place March 26-28, 2014 at INM - Leibniz Institute for New Materials in Saarbrücken, Germany. This will be the 4th edition of the annual Nanobrücken workshop series. This year's Keynote Speaker will be Andrew Minor (University of California, Berkeley).

The Department of Civil and Environmental Engineering at the National University of Singapore (NUS) is recruiting 2 post-doctorate research fellows to pursue research on ice-structure interaction in the Keppel-NUS Corporate Laboratory. As part of the S$75 million collaboration between Keppel Corporation and NUS, the team comprising of Prof. Andrew Palmer, Dr. Bai Wei, and Dr. Pang Sze Dai, seeks to develop solutions for offshore rigs to meet the challenges of harsh arctic environments in oil and gas exploration and production.

I have updated my notes on the Griffith paper.  I added more description on the experimental determination of surface tension of solids.  Griiffith himself determined the surface tension of glass by an experimental setup.  Udin et al (1949) described a setup based on the same principle.  This setup is now known as the zero creep experiment.

In 2012 and 2013 we organized very successful Workshops on
"Physics-based material models and experimental observations" funded
by the European Union's Enlargement programme. We cordially invite you to
submit an abstract to the 3rd International Workshop on Physics Based
Material Models and Experimental Observations to be held on 2-4 June
2014 in Cesme-Izmir/Turkey.

Lecturers:

Basile Audoly - Université Pierre et Marie Curie and CNRS, Paris, France

Katia Bertoldi - University of Harvard, Cambridge, MA, USA

Davide Bigoni - Università di Trento, Italy

Alain Goriely - University of Oxford, UK
