The Effect of Strain Rate on the Deformation Processes of NC Gold with Small Grain Size

open access: yesCrystals, 2020
The strength of nanocrystalline (NC) metal has been found to be sensitive to strain rate. Here, by molecular dynamics simulation, we explore the strain rate effects on apparent Young’s modulus, flow stress and grain growth of NC gold with small size. The

Effect of grain size on the strain rate sensitivity of CoCrFeNi high-entropy alloy

open access: yes, 2020
Strain rate sensitivity (SRS) of a face-centered cubic (fcc) CoCrFeNi high-entropy alloy (HEA) with grain sizes ranging from 57 μm to 45 nm was investigated using nanoindentation, and was compared with those reported for conventional fcc metals ...

Thickness-Dependent Strain Rate Sensitivity of Nanolayers via the Nanoindentation Technique

open access: yesCrystals, 2018
The strain rate sensitivity (SRS) and dislocation activation volume are two inter-related material properties for understanding thermally-activated plastic deformation, such as creep. For face-centered-cubic metals, SRS normally increases with decreasing

Strain-rate sensitivity of glasses

open access: yesJournal of Non-Crystalline Solids, 2014
AbstractWe report on the loading-rate dependence of localized plastic deformation in inorganic covalent, metallic, ionic and superionic glasses. For this, the strain-rate sensitivity is determined through instrumented nanoindentation in a load-controlled strain-rate jump test. Through relating the strain-rate sensitivity to the reduced temperature, the

Compressive strain rate sensitivity of ballistic gelatin

open access: yesJournal of Biomechanics, 2010
Gelatin is a popular tissue simulant used in biomedical applications. The uniaxial compressive stress-strain response of gelatin was determined at a range of strain rates. In the quasistatic regime, gelatin strength remained relatively constant. With increase in loading rate, the compressive strength increased from 3kPa at a strain rate of around 0 ...
