The international CNRS-funded network “GDRi MECANO” is now close to the end of its 4 years of existence (2012-2015).
This network focuses on the issue of mechanical properties in small dimensions. MECANO is a multidisciplinary network, which brings together physicists, mechanical engineers and chemists. The scientific questions raised by the issue of size effects on mechanical properties are many fold: one has – as always in nanoscience - to question how the basic theories we use at the macro- and meso- scales (plasticity, continuum elasticity, etc) apply at the nanometre scale. But studying mechanical properties of nanosize objects challenges also the experimental tools one needs to use: how to implement reproducible and controllable mechanical loading? How to measure fields (displacement, stress, strain, etc) with the required nano-resolution ? Moreover nanoscience is often tackling the limits of continuum theories and thus simulation is an increasingly important tool to evaluate the different scale changes needed (from atoms to nano-objects). Finally most nano-objects are man made and the way they are grown or fabricated greatly influences their properties. Last but not least mechanics at the nanoscale is an important issue in various technologies. This concerns the reliability of the devices but also the enhancement of performances caused by strain. The Marseille meeting will be the opportunity to discuss about the main achievements and challenges as well as to prepare the next 4 years.
This general meeting will take place on November 5-6, 2015, hosted by Im2np. The main topics will be :
- Simulation of mechanical properties (ab-initio, MD, DDD, FEM…)
- Small Scale Mechanics (elasticity, plasticity, fracture, creep…)
- Mechanical testing (Nano-indentation, MEMS, AFM…)
- Micro/Nano-Diffraction (coherent diffraction, Laue…)
- Micro/Nano-Microscopy (TEM, EBSD…)
- Synthesis of Nano-objects/Films/Multilayers
- Internal Stresses and Phase Transformations (growth stress, interfaces, instabilities, …)
A special workshop dedicated to the MECANIX ANR-funded project (Mechanics of Nanostructures probed In-situ by X-rays: In situ evaluation of strain and defects in nanostructures during mechanical loading) will also be organized.
