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

Investigation on the Strain Rate Sensitivity of Polytetrafluoroethylene
DEStech Transactions on Engineering and Technology Research, 2018 Strain rate sensitivity of polytetrafluoroethylene(PTFE) across strain rate range from 10-3 to 106 s-1 was investigated. For quasi-static state of strain rates from10-3 to 10-1 s-1, the samples were tested using universal material testing machine. The values of compression strength and Young’s Modulus were calculated from the experimental results.
