Nanoindentation is a technique that has been broadly applied to characterize the mechanical properties of materials with high spacial resolution. The basic concepts used to accurately apply the technique, as well as some of the newest measurement frontiers being explored today, will be presented in this webinar. The process of converting load versus displacement measurements to materials properties through an understanding of the geometry associated with the experiments is the basis for these experiments. The newest techniques that will be mentioned include in-situ experiments in electron microscopes, testing at elevated temperatures and high-speed testing for the mapping of properties. The challenges associated with these frontiers will be briefly discussed.
