Dynamic nanoindentation by instrumented nanoindentation and force microscopy: a comparative review [PDF]

open access: yesBeilstein Journal of Nanotechnology, 2013
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 ...

Analysis of Nanoindentation Test Results of Asphalt Mixture with Different Gradations

open access: yesApplied Sciences, 2021
Nanoindentation has been applied in the field of asphalt mixtures, but, at the nano-scale, changes in the composition of the mixture and material properties can have a significant impact on the results.

Ferrule-top nanoindenter: An optomechanical fiber sensor for nanoindentation [PDF]

open access: yesReview of Scientific Instruments, 2012
Ferrule-top probes are self-aligned all-optical devices obtained by fabricating a cantilever on the top of a ferruled optical fiber. This approach has been proven to provide a new platform for the realization of small footprint atomic force microscopes (AFMs) that adapt well to utilization outside specialized laboratories [D. Chavan et al., Rev.

INFLUENCING THE INDENTATION CURVES BY THE BLUNTNESS OF THE BERKOVICH INDENTER AT THE FEM MODELLING

open access: yesActa Polytechnica CTU Proceedings, 2020
The influence of the Berkovich indenter bluntness on the indentation curves at nanoindentation test of fused silica is determined by the FEM (finite element method) in this paper. The Berkovich indenter, which is mostly used for the nanoindentation test,

Review of Nanoindentation Size Effect: Experiments and Atomistic Simulation

open access: yesCrystals, 2017
Nanoindentation is a well-stablished experiment to study the mechanical properties of materials at the small length scales of micro and nano. Unlike the conventional indentation experiments, the nanoindentation response of the material depends on the ...

Calibration of a Constitutive Model from Tension and Nanoindentation for Lead-Free Solder

open access: yesMicromachines, 2018
It is challenging to evaluate constitutive behaviour by using conventional uniaxial tests for materials with limited sizes, considering the miniaturization trend of integrated circuits in electronic devices.

Evaluating local strain rate sensitivity of titanium alloy using dynamic nanoindentation testing

open access: yesMeasurement: Sensors, 2021
Constant strain rate nanoindentation testing is useful for evaluating local strain rate sensitivity. In titanium alloys, the dwell fatigue at room temperature is a critical issue, and this phenomenon is known as relating to local strain rate sensitivity.

Nanoindentation of embedded particles

open access: yesJournal of Materials Research, 2023
AbstractWe address the effect of elastic inhomogeneity on elastic modulus and hardness determinations made by depth-sensing indentations performed on individual particles embedded within a matrix of different elastic modulus. Finite element simulations and nanoindentation experiments are used to quantify the consequences of particle/matrix elastic ...
