The entire stress-strain curve can now be determined using nanoindentation with a flat-ended cylindrical punch and novel analysis of the resulting force-displacement data 1. Unlike pyramidal indenters ...

Three samples of shale rock, two from the Eagle Ford play and one from the Haynesville play, were successfully tested by instrumented indentation using a Nano Indenter G200 from KLA. Results were ...

The nominal stress-strain curves of an oxidized Zr-Cu-Al-Ni nanotube (left) and a comparison of various metals with respect to their recoverable elastic strains (right). Image must be used with ...

Yield stress is the stress at which the breakdown of the structural frame occurs, and the related strain is the yield strain. Figure 1 represents the mechanical analogues depicting the process with ...
