Compressive strain rate sensitivity of ballistic gelatin
Journal 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 ...

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

Modeling strain rate sensitivity and high temperature deformation of Mg-3Al-1Zn alloy
Journal of Magnesium and Alloys, 2019 Increasing the plastic deformation temperature of Mg alloys results in higher strain rate sensitivity, easier activation of secondary slip modes, and impeded twinning. In this study, the strain rate sensitivity is estimated for each deformation mode, and
