Symposium Mechanical Behavior at the Nanoscale V
Presentation Title Recent Innovation in In-situ Extreme Mechanics at the Micro and Nanoscale

On-Site Speaker (Planned) Nicholas X. Randall
Abstract Scope This talk will focus on recent developments in instrumentation for in-situ extreme mechanics testing at the micro and nanoscales, focusing on a testing platform capable of strain rate testing from 0.0001/s up to 10’000/s (8 orders of magnitude) with simultaneous high speed actuation and sensing capabilities, with nanometer and micronewton resolution respectively. Other recent innovations include cryogenic and high temperature tests covering the envelope from -150 to 800 °C. The challenges in variable temperature tests and the associated technological and protocol advances will be discussed along with select case studies. The inherent advantages of using small volumes of sample material, e.g., small ion beam milled pillars, will be discussed together with the associated instrumentation, technique development, data analysis methodology and experimental protocols. Some examples will be presented where a wide range of strain rate has been combined with variable temperature to investigate rate effects as a function of temperature.
