Since its development in the mid-1980's, nanoindentation has proven to be an important tool for exploring and characterizing the small-scale strength and mechanical behavior of a wide variety of materials. Some of these are quite unusual, either because the materials themselves are out-of-the-ordinary or because their mechanical behavior at the micro- and nano-scales is different from that of the bulk. For example, small pillars of pure metals with diameters of approximately one micrometer can have strengths 10 to 100 times greater than their macroscopic counterparts.

In this presentation, a series of examples is used to illustrate some of the unusual mechanical behavior observed at small scales along with the scientific reasons for them. The examples are taken from a diverse set of disciplines including materials science, biology, geology, and medicine, all of which have benefited enormously from recent advances in nanomechanical testing.
