Symposium Technical Description

Decreasing dimensions of microelectronic and micromechanical devices have motivated research on the mechanical and physical properties of materials at micro- and nano-scales. However, it is difficult to precisely measure the properties of small-scale materials with conventional apparatus used for bulk materials. In addition, probing micro- and nano-samples is challenging due to the inherent difficulties associated with the fabrication and handling of extremely small specimens. Therefore, new experimental methods with enhanced characterization capabilities are required to better understand the properties and deformation mechanisms of technologically relevant materials. The Materials Genome Initiative (MGI) and Integrated Computational Materials Engineering (ICME) program also call for the development of creative and high throughput experimental methodologies to serve as a benchmark for computational simulations.

This symposium will focus on sharing new instrumentation and fabrication techniques to measure properties of materials/structures at different length scales, loading, and environment conditions. Topics in this symposium will include but are not limited to the: (a) design and manufacture of custom loading frames; (b) advanced fabrication of sensors and actuators to measure mechanical and physical properties of materials; (c) mechanical and physical properties of small-scale materials in extreme environments; and (d) reliability studies of applied materials embedded in complex structures.

We anticipate the speakers to convey new ideas and to interact with the audience by sharing experiences in overcoming the technical challenges in their research.
