The Grand Challenge of the MecaNano COST Action is to consolidate the existing findings and increase the throughput of the research community to gain a scale-bridging mechanical understanding of how the nanoscale behaviour gives rise to the macroscopic properties of modern nanostructured materials. The MecaNano Action will divide the Grand Challenge into five sub-challenges, as depicted on Fig 1.
Research efficiency and synergies between different fields are impeded by a lack of agreement on the level of granularity to pursue. Granted, it would be a squander of resources to measure or model every single atom of every good understanding of their mechanical behaviour. At the macroscopic scale, aggregate properties (e.g. strength, fracture toughness) perform fairly well at predicting the overall behaviour, at least in homogeneous materials subjected to simple loading. With regard to nanostructured materials, which encompass strongly interacting microscale volumes of different constituents and suffer from size effects, these aggregate parameters break down. There is an acute need to agree on the critical length scale at which mechanical properties can still be robustly defined, i.e. to define a common nanomechanical quantum.
