While a great deal of progress has been made in understanding the theoretical fundamentals of nanodevices and nanomaterials, to date the complexities of performing mechanical experiments at the nanoscale have limited the ability to compare theoretical and computational predictions with experimental data. In this chapter we will discuss some of the critical challenges that hamper mechanical experiments at the nanoscale, and present how these challenges have been, and are currently being, addressed by next-generation tools designed to perform nanoscale mechanical experiments. In particular, we will focus on how our work and understanding have evolved through our experience in this area. We will then present a number of examples of how our current nanomanipulator has been used to perform nanoscale mechanical testing of a variety of nanostructures, including: tensile loading of individual nanostructures, nanoscale pullout tests of nanostructures embedded in a matrix material, and forced vibrational resonance to measure the modulus of nanorods and nanotubes. We will conclude by discussing relevant near- and long-term goals and challenges of nanoscale mechanical experimentation. [ABSTRACT FROM AUTHOR] |
