Influence of strain rate sensitivity on localization and void coalescence [PDF]

open access: yesInternational Journal of Plasticity, 2020
The onset of macroscopic strain localization limits the ductility of many ductile materials. For porous ductile materials, two distinct mechanisms of macroscopic localization have been identified: void growth induced softening and void coalescence. In this work we focus on analyzing the influence of material's strain rate sensitivity (SRS) on the two ...

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

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 Aging Process on the Strain Rate Sensitivity in V-Containing TWIP Steel

open access: yesMetals, 2021
The dynamic tensile behavior of the twinning-induced plasticity (TWIP) steel with the vanadium carbide is investigated at different strain rates of 10−4, 10−3, 10−2 and 0.05 s−1.

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 ...

On the strain-rate sensitivity of columnar ice [PDF]

open access: yesJournal of Glaciology, 1997
AbstractA power law relation between stress and strain rate of the form was used to describe the response to strain rate of S1 ice loaded across the columns at –10° C. The rate exponent, n, decreased with increasing strain from about 4.6 at an observed peak on the load displacement curve to approximately 2.6 at a shortening of 2%.
