Operant strain-rate sensitivity during tensile necking
Metallurgical Transactions A, 1983Precisely machined tensile specimens of aluminum-killed steel sheet were used to measure the continuous strain-rate sensitivity,m c, in a series of isothermal tests at different crosshead speeds.m cwas found to be independent of strain and strain rate, in contrast with the “jump” test instantaneous strain

Strain hardening, strain rate sensitivity, and ductility of nanostructured metals
Materials Science and Engineering: A, 2004This paper presents an overview of the strain hardening and strain rate hardening behavior of nanostructured and ultrafine-grained metals. The experimental findings obtained in our laboratory are summarized, with some recent data for ultrafine-grained Cu presented as a model case.

The strain-rate sensitivity of α-uranium
Journal of the Mechanics and Physics of Solids, 1959Abstract Experiments are described in which specimens from two different batches of uranium were subjected to both static and dynamic compression tests. From such tests static and dynamic stress-strain curves were obtained. These stress-strain curves indicate that α-uranium is slightly strain-rate sensitive; for instance, the effect of increasing ...

Strain hardening, rate sensitivity, and gradient plasticity
2023Abstract Models of strain hardening and rate sensitivity are described. The classical model of isotropic hardening, applicable to any kind of material symmetry, is discussed, together with the modeling of the elastic-viscoplastic response of isotropic and crystalline materials.

Strain Rate Sensitivity of Commercial Aluminum Alloys
2019This article presents a review of the strain rate-dependent mechanical behavior of aluminum and its commercial alloys. The importance of strain rate sensitivity (SRS) stems from its relation with ductility and formability. Plastic deformation is stable and localization less likely in alloys with higher SRS.

Strain rate sensitivity of Ge-Se glasses
2018Chalcogenide glasses are widely used in optical applications either as information carrier or as sensors due to their optical transparency in the mid-infrared window (8-15 µm), high refractive index and non linearity. Glasses from the GexSe1-x system have been extensively studied over the last decades because some of their physical properties do show ...
