Ultra High Strain Rate Nanoindentation Testing. [PDF]
Materials (Basel), 2017 Strain rate dependence of indentation hardness has been widely used to study time-dependent plasticity. However, the currently available techniques limit the range of strain rates that can be achieved during indentation testing. Recent advances in electronics have enabled nanomechanical measurements with very low noise levels (sub nanometer) at fast ...

Image-based high strain rate testing of orthopaedic bone cement
EPJ Web of Conferences, 2018 Bone cement is widely used for the fixation of orthopaedic implants. It is a multi-component material that consists of a PMMA base with a small proportion of (usually ceramic) radiopacifier to enable the cement to be observed by X-ray.

Twin recrystallization mechanisms in a high strain rate compressed Mg-Zn alloy
Journal of Magnesium and Alloys, 2021 Static recrystallization of a high strain rate compressed Mg-1 Zn (wt.%) alloy was investigated using electron backscattered diffraction (EBSD). A novel 53°〈101¯0〉 structure was observed in the as-deformed alloy, which showed a {101¯2}-{101¯2} double ...
