There is an increasing demand, both from industry and research community, to characterize small-scale and site-specific mechanical properties of materials.
The motivation behind such demand is two folds:
- the need to reliably predict the performance of miniature mechanical systems (MEMS, UV-LIGA watch parts, coated components like machining tools etc.) and microelectromechanical systems (MEMS/NEMS/MOEMS);
- to develop detailed and accurate hierarchical models of the mechanical behavior of complex, multicomponent structural materials.
This requires the development of new micro-scale instruments and testing methods to study the deformation behavior of small mechanical parts and to investigate size effects in mechanical properties.
