On uncertainty of elastic modulus measurements via nanoindentation mechanical testing and conventional triaxial testing

Journal of Rock Mechanics and Geotechnical Engineering
Geomechanical properties of rocks vary across different measurement scales, primarily due to heterogeneity. Micro-scale geomechanical tests, including micro-scale “scratch tests” and nano-scale nanoindentation tests, are attractive at different scales ...

Nanoindentation Ontology: Harmonising knowledge and data for nanoindentation

Zenodo
This is a poster that was presented that the MecaNano conference 2024. https://mecanano2024.sciencesconf.org/  In the field of nanoindentation, a critical challenge has been the lack of standardized terminology and data interpretation frameworks, hindering effective collaboration and replication of experiments across different laboratories. To address

Effect of Cu and CuP Additions on the Microstructure and Nanoindentation‐Based Fracture Behavior of CoNiAlSi Ferromagnetic Shape Memory Alloys

Advanced Engineering Materials, EarlyView.
Cu and combined Cu–P microalloying refine the microstructure and enhance the nanoindentation‐derived fracture resistance of CoNiAlSi ferromagnetic shape memory alloys without suppressing the martensitic transformation. Comparative SEM, DSC, and nanoindentation results reveal that the CuP‐containing alloy provides the most balanced response, achieving ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

Advanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Study on elastic-plastic behaviour of inclusions in cold drawn wire by using reverse analysis and nanoindentation test

MATEC Web of Conferences, 2015
The purpose of this study is to investigate the elastic-plastic behavior of inclusions, i.e. SiO2 particles, in cold drawn wire using reverse analysis and nanoindentation test. First, the nanoindentation tests were performed to obtain indentation load P –

Glissile Interphase Boundaries Enable Collective Phase Switching in Epitaxial Polar Oxides

Advanced Functional Materials, EarlyView.
A triple point is identified in the phase diagram of low‐symmetry epitaxial BiFeO3 thin film along with an extended regime of phase competition associated with a flattened energy landscape. The electromechanical response is shown to be governed by correlated interphase‐boundary motion, including scale‐free avalanche dynamics characteristic of systems ...
