Understanding True Stress and True Strain
Did you know that the typical stress-strain curve obtained from a uniaxial tensile test is just an approximation? It doesn't consider the fact that the dimensions of the test specimen change ...
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 ...
In Session 23 of the KLA Instruments Indentation University series, nanoindentation measurement of the yield stress-strain curve is demonstrated using the iMicro nanoindenter on Ti-6Al-4V, and ...
