<p>Nanoindentation at high strain rates presents additional challenges over traditional quasi-static indentation, including the need for high-speed electronics, fast feedback, well-characterized dynamics, and new analysis methods. High strain rate indentation is important for analyzing material behavior at rates observed in many real-life processes, such as impacts in automotive or aerospace applications. Here, two prominent analysis methods for high strain rate nanoindentation are presented in detail and used to analyze the high strain rate nanoindentation data on tungsten performed at high temperatures. Nanoindentation at quasi-static rates on fused quartz shows that the assumption in one of the analysis methods is violated. This same violation was observed in tungsten. Nevertheless, the analysis methods were used to calculate strain rate sensitivity at high strain rates and elevated temperature on tungsten. Despite the assumptions being violated, both analysis methods can be employed to accurately calculate derived quantities such as the strain rate sensitivity.</p>
