Evaluating local strain rate sensitivity of titanium alloy using dynamic nanoindentation testing
Measurement: Sensors, 2021 Constant strain rate nanoindentation testing is useful for evaluating local strain rate sensitivity. In titanium alloys, the dwell fatigue at room temperature is a critical issue, and this phenomenon is known as relating to local strain rate sensitivity.

The Effect of Strain Rate on the Deformation Processes of NC Gold with Small Grain Size
Crystals, 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
