Instrumented nanoindentation is a valuable method for mechanical characterization. Typically, sharp tips are used to indent surfaces and wellestablished techniques used to determine the hardness and moduli values of a wide range of materials. Spherical indentation tips, though less common, offer the distinct advantage of providing useful insight into ...

Piezoelectric nanoindentation (PNI) has been developed to quantitatively address electromechanical coupling and pressure-induced dynamic phenomena in ferroelectric materials on the nanoscale. In PNI, an oscillating voltage is applied between the back side of the sample and the indenter tip, and the first harmonic of bias-induced surface displacement at

The nanoindentation behaviours of single crystalline silicon samples has gained wide attention in recent years, because of the anomaly effects in the loading curve, caused by the pressure induced phase transformation of silicon. To further enlighten the phenomenon bulk, ion-implanted, single crystalline Si samples have been studied by nanoindentation ...

This present work focuses on the surface characterization of reactor-thermoplastic-polyolefin copolymers (R-TPO) for automotive applications to deduce an appropriate parameter as a measure of the surface stickiness behavior. Therefore, nanoindentation experiments are performed and the well-known mechanical contact properties have been determined ...

Nanoscratching meets nanoindentation
Zeitschrift für Kristallographie - Crystalline Materials, 2016AbstractA specimen of high-carbon nitrogen-doped steel has been synthesized to supplement previous studies on wootz-like steels. A comparison of different states of material as well as one of distinct methods of hardness testing has been performed. Electron microscopy of the specimens’ microstructure revealed nano-structuring similar to that observed ...

Nanoindentation of dental composites
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2005AbstractThe intent of this project was to evaluate the elastic modulus and hardness of four composites with different fillers, a microfill, a hybrid, a dental resin cement, and a fiber filler, using nanoindentation. An indentation load of 0.001 N was used and 100 indents per specimen were taken. The elastic modulus measured for the Choice composite was

Time-Dependent Nanoindentation
2004In general, materials can resist deformation in a solid-like or viscous-like manner. Solid-like materials store energy under deformation, and upon removal of stress, returns to its original state. Viscous materials dissipate energy during deformation and upon removal of stress, remains in its deformed state.

Small-scale polymers are increasingly being applied to a variety of fields, making it important to understand the behavior of polymers at small length scales. Indentation size effects (ISE) is the apparent increase in material-specific properties at very low indentation depths.
