In nanoscience, one always has to question how the basic theories wee use at the macro-and-meso-scales (continium elasticity and plasticity, etc) apply at the nanometre scale. Studying mechanical properties of nano-size objects also challenges the experimental approaches: 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 continiuum theories and simulation is an increasingly important tool to evaluate the different scale transitions needed from atoms to nano-objects.
This book provides an updated view of the rapidly growing field of mechanical properties of nano-objects like micropillars, nanowires, nano-particles, nano-precipitates, nano-twins, MEMS, NEMS and structured surfaces, etc. It adresses the theorical and experimental issues that span the fieldof mechanics at small dimensions : the fundamentals of continuum mechanics and the mechanics of defects, a general state-of-the-art about modelling and simulation and a overview of the size dependent mechanical properties of nano-objects. Fascinating recent advances are shown in the evaluation of displacement fields at the nano scaleby X-ray diffraction and transmission electron microscopy. Examples are given of systems where mastering mechanical properties in small dimensions is key to control the final aimed property (electrical, optical, mechanical, etc).
Olivier Thomas (IM2NP, Aix-Marseille University, CNRS), Anne Ponchet (CEMES, CNRS), Samuel Forest (MINES ParisTech, CNRS) coordinate the CNRS research network MECANO gathering specialists in physics, mechanics and chemistry investigating size dependent properties of materials. This book results from a spring school, which took place in Autrans on the Vercors plateau close to Grenoble, France from March 14 to March 19, 2010.
