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 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 ...

The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...

The elastic modulus relates the applied stress to the strain it produces. In a material that obeys Hooke's Law, the initial uniaxial elastic response is linear with stress and strain coupled through ...

Plastometrex develops ASTM Standard for PIP testing, giving engineers and researchers a trusted route to cost-effective ...

Because of their very large molecular weight (~ 10 6) polymers behave differently from the low molecular weight metals during plastic deformation leading to a ductile fracture. The top diagram shows a ...

SAE International Journal of Materials and Manufacturing, Vol. 7, No. 2 (April 2014), pp. 446-453 (8 pages) ABSTRACT Light weight alloys are widely used in the automotive industry in order to meet ...
