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 ...

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.

Analysis of nanoindentation of soft materials with an atomic force microscope [PDF]

open access: yes, 2011
Nanoindentation is a popular experimental technique for characterization of the mechanical properties of soft and biological materials. With its force resolution of tens of pico-Newtons, the atomic force microscope (AFM) is well-suited for performing ...

Unraveling deformation mechanisms around FCC and BCC nanocontacts through slip trace and pileup topography analyses [PDF]

open access: yes, 2017
Nanocontact loadings offer the potential to investigate crystal plasticity from surface slip trace emissions and distinct pileup patterns where individual atomic terraces arrange into hillocks and symmetric rosettes.

Effect of Morphological Changes due to Increasing Carbon Nanoparticles Content on the Quasi-Static Mechanical Response of Epoxy Resin [PDF]

open access: yes, 2018
Mechanical failure in epoxy polymer and composites leads them to commonly be referred to as inherently brittle due to the presence of polymerization-induced microcrack and microvoids, which are barriers to high-performance applications, e.g., in ...

The influence of indenter tip rounding on the indentation size effect [PDF]

open access: yes, 2010
A model was developed to interpret the indentation size effect. The model considers the tip wear effect, causing a rounded tip, the plastic zone size and various strengthening contributions, including geometrically necessary dislocations, preexisting ...

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 ...

Nanoindentation of bone: Comparison of specimens tested in liquid and embedded in polymethylmethacrylate [PDF]

open access: yes, 2004
Elastic modulus of bone was investigated by nanoindentation using common methods of sample preparation, data collection, and analysis, and compared to dynamic mechanical analysis (DMA: three-point bending) for the same samples. Nanoindentation (Berkovich,

Mechanical characterization of solution-derived nanoparticle silver ink thin films [PDF]

open access: yes, 2007
Mechanical properties of sintered silver nanoparticles are investigated via substrate curvature and nanoindentation methods. Substrate curvature measurements reveal that permanent microstructural changes occur during initial heating while subsequent ...

Analytical modeling of surface roughness in precision grinding of particle reinforced metal matrix composites considering nanomechanical response of material [PDF]

open access: yes, 2019
Grinding is usually applied for particle reinforced metal matrix composites (PRMMCs) to achieve high ground surface quality. However, the surface quality especially surface roughness is difficult to predict theoretically due to different mechanical ...
