Abstract Scope |
The strain rate dependence of mechanical properties of materials at high strain rates is of great interest for many applications including metal forming, machining, crashworthiness, projectile impact, etc. It is therefore desirable to extend nanoindentation to strain rates beyond the quasi-static regime, taking advantage of a well-established technique with relatively simple sample preparation, high-throughput testing capabilities and comparably small equipment.
This talk will focus on recent developments in instrumentation and testing protocols for high strain rate testing from 0.0001/s up to 10’000/s with high-speed actuation and sensing capabilities. Moreover, we will elaborate on high strain rate testing performed at high and low temperatures as well as under variable humidity, and how the resulting multidimensional data is useful for understanding fundamental material behaviour and advancing engineering objectives. The challenges of such experiments and the associated technological and test protocol advances will be discussed along with select case studies. |
