Dynamic Nanoindentation

This paper investigates methods of improving measurement interpretations in dynamic nanoindentation. In particular, a shift in the system's primary resonance is observed experimentally and investigated through modeling and numerical studies. The result of these investigations is that different sources of nonlinearity, namely, nonlinearities from the tip-sample contact force and the indenter's capacitive transducer, compete to alter the system's primary and secondary resonances. Furthermore, this study implies that the accurate characterization of a material surface requires the implementation of higher fidelity models that include nonlinear expressions, as opposed to linearized versions, for the tip-sample contact force and transducer electrostatic force.

Dynamic Nanoindentation

Viscoelasticity is a complex yet important phenomenon that drives material response at different scales of time and space. Burgeoning interest in nanoscale dynamic material mechanics has driven, and been driven by two key techniques: instrumented nanoindentation and atomic force microscopy. This review provides an overview of fundamental principles in nanoindentation, and compares and contrasts these two techniques as they are used for characterization of viscoelastic processes at the nanoscale.

ABSTRACTThis paper describes a new method of dynamic nanoindentation testing whereby, instead of the imposition of a single sinusoidal modulation onto the driving force signal, a multiple-frequency modulation is applied and a Fourier analysis used to extract frequency-dependent mechanical properties. The instrument response is cancelled by the use of a reference transfer function using an equalization process. The present work gives details of the method and presents some example measurements.
