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 diagram opposite shows force-displacement data obtained on an aluminum sample. In order to convert this into an engineering stress-strain curve the force must be normalized with the initial ...
A neck is formed in a tensile test specimen when the UTS of the engineering stress/strain curve is reached. Prior to this stress-strain condition the plastic deformation occurs throughout the sample ...
