Size Effects in Mechanical Properties

Objective

The aim of NANOMESO is to develop knowledge in nano-micromechanics and to develop a validated computational tool to understand and predict unique plasticity phenomena experimentally observed. In nanotechnology object scales are determined by optimised fun ctionality resulting in ever shrinking sample size dimensions to the sub-micron regime and decreasing structural length scales such as grain size to the nanometer regime. The experimentally observed size dependent plasticity is not explained by existing th eories. Since the mechanism occurring span multiple time and length scales, a multiscale computational approach is required where knowledge is transferred from ab-initio across atomistics to the mesoscale (sub-micron-scale). The atomistic pathways and ener getics of the deformation mechanism in confined systems with interface dominated structures will be determined and implemented in a dislocation dynamics code allowing simulation of mechanical behaviour in a one-to-one scale with experiment. The NANOMESO consortium involves leading-edge US and EU theoreticians and modellers that have already a great expertise in the field. The full integration of two leading experimental groups in nano-micromechanics into the project (with national financial support) and t he EU-project leader having an international reputation for both computational and experimental approaches in nano-micromechanics, guarantees maximum synergies between experiment and modelling. The performance-oriented objectives are advancing the front iers of knowledge in multifunctional materials science. NANOMESO will help to overcome the initial barrier that usually prohibits or decelerates the use of novel materials/components due to a lack in theory/understanding. NANOMESO will support long-term in novation relevant to industrial applications of multifunctional metallic components such as in MEMS-devices by constructing a predictive tool, lowering investment costs for European industry.
