Abstract

Dynamic nanoindentation was preformed on a cured epoxy, poly(methyl methacrylate), and poly(dimethyl siloxane) or PDMS. These samples, two glassy polymers and a rubbery material are used to illustrate the agreement between classical rheological instrumentation and dynamic nanoindentation. Excellent agreement between bulk rheological data and the dynamic nanoidentation data for the two glassy materials and more divergent results for the rubbery PDMS was observed. Also discussed is the theoretical foundation and historical development of the working equations for these two types of instrumentation. The major difference between nanoindentation and the more classical rheological instrumentation is in the instrument-sample interface.
