Webinar : Algorithms for Nanoindentation Straing Rate Jump Testing

Webinar : Algorithms for Nanoindentation Straing Rate Jump Testing

Date: Friday 31 March

Time: 5am NZDT, 3am AEDT, 12 midnight AWST
 

Thermally activated deformation processes control plasticity and fracture in many materials, including body-centered cubic (BCC) metals, and can be probed via the strain rate dependence of their yield stress. One technique to probe this is the strain rate jump test, in which the strength change at an abrupt change in applied strain rate is measured, which has traditionally been performed on the bulk scale, but requires large samples and cannot measure local properties. Nanoindentation solves both of those issues.

This webinar will discuss testing methods for strain rate jump tests using the Bruker Hysitron TI 980, as well as functions to perform necessary corrections to the data. The functions were validated using single crystalline BCC tungsten as a model material, so application to other material systems will be discussed.
