Experimental Approach to Fracture Mechanics in Nanometer Scale

The experimental requirements to understand the strength of bulk material have been intensively investigated in terms of the solid mechanics and the knowledge for evaluating the main characteristics are already standardized from macroscopic viewpoints. On the other hand, in recent years, industrial needs as well as academic interests require the mechanical testing in micro- and nano-scale materials and extensive effort has been conducted for the development of methodology. It is not only because of further evolution in small devices such as electronic devices and MEMS/NEMSs but also because of multiscale modelling for a large component for precise design based on the numerical simulations. The miniaturization scale in testing methodology is reaching at almost nanometer order. (C) 2018 The Authors. Published by Elsevier B.V. Peer-review under responsibility of the ECF22 organizers.
