The macroscopic behaviour of Engineering Materials depends on their microstructure and on the behaviour of their phases or micro-constituents.  Any material is heterogeneous beyond a given length scale, from the macroscale (composites with different phases) to the microscale (polycrystals) and the nanoscale (defects in crystalline solids: dislocations, precipitates, etc).  A correct understanding and modelling of the behaviour at low lengths scales (nano to micro) is the basis to understand the macroscopic behaviour and to build physically based constitutive models. Moreover, device dimensions rapidly decrease to nano-microscale dimensions (thin films, nanowires, NEMS) and their mechanical/physical simulation can only be achieved with models that account for their low scale microstructure.This symposium aims at bringing together modelling groups of the micro- and nanomechanics community working on the simulation of materials at the nano-micro scales. Contributions are welcomed from groups working on modelling techniques, particularly the following ones:

1)    Molecular dynamics

2)    Kinetic Monte-Carlo methods

3)    Dislocation dynamics

4)    Crystal plasticity models
