Strain rate dependency of dislocation plasticity [PDF]
Nature Communications, 2021 The relationship between the strain rate and micro-scale deformation in metals is still poorly understood. Here the authors use discrete dislocation dynamics and molecular dynamics to establish a universal relationship between material strength ...

Strain and strain rate in friction extrusion
Journal of Materials Research and Technology, 2022 Friction extrusion is a metal forming process that generates large plastic strains and deformation-induced heating through friction between a rotating die and the material to be extruded.

Strain and strain rate: An emerging technology in the perioperative period
Annals of Cardiac Anaesthesia, 2016 Newer noninvasive parameters are being used for perioperative detection of myocardial ischaemia. TDI and global strain rate are some of these parameters. TDI signal is a modification of the routine Doppler flow signal.

Ultrahigh high-strain-rate superplasticity in a nanostructured high-entropy alloy
Nature Communications, 2020 Superplasticity describes a material’s ability to sustain large plastic deformation in the form of a tensile elongation to over 400% of its original length, but is generally observed only at a low strain rate (~10 −4 s −1 ), which results in long ...
