Nanomaterials and advanced characterization

Advanced small-scale mechanical characterization: strength, plasticity, fracture and fatigue

Thin films, coatings, welds, flexible electronics, sensors and MEMS rank among the most critical components made of small volumes of materials used in a variety of applications (automotive, energy, nuclear, microelectronics, aerospace...). Ensuring their service performance and lifetime requires detailed knowledge about the small-scale mechanical behaviour of materials, which can only be gained through advanced experimental and/or simulation methods.

Scope:

The small-scale mechanical characterization of materials relies upon the development and use of a wide range of highly specialized experimental and simulation techniques, aimed at investigating different mechanical aspects. Past research has mostly focused on the yield behavior of single crystalline microsized structures. Although they represent a big initial step toward a better understanding of mechanical size effects, these investigations were very limited in scope regarding both the kind of failure and the type of microsamples. The present symposium will focus on recent developments aimed at expanding our knowledge to the behavior of more complex specimens (for instance nano-objects, thin films and bulk nanostructured materials) and/or under more complex loading conditions (including cyclic fatigue, fracture testing...). To date, the most promising investigations build upon the combination of mechanical testing either with in-situ characterization methods (such as TEM, SEM, AFM, micro-XRD, synchrotron, electrical measurements) or with simulation methods (such as for instance atomistic simulations and discrete dislocation dynamics). The symposium highly welcomes such contributions, which are well suited for gaining a deep insight into the mechanisms responsible for mechanical size effects. Direct applications of these methods to solve complex engineering issues are also warmly welcomed.
