Spherical nanoindentation

2021
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

Journal of Materials Research, 2006
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

Nanoindentation of Silicon

Materials Science Forum, 2008
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 ...

Nanoindentation of polymers

Meccanica, 2011
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 ...
