When a material experiences an applied uniaxial tensile stress, s, it displays a strain response, e. In the initial stage of strain, the response is linear in the stress and may be described by ...

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 ...

Oscillation Amplitude Sweep The oscillatory stress or strain is increased in this method, and the resulting changes in the elastic modulus (G') or the elastic stress (σ') due to increasing amplitude ...

In this paper we consider a statistically homogeneous medium with small random variations in elastic properties. We derive the equations satisfied by the two point displacement field correlation ...

The tensile behavior of composites is also different from that of metals in the 'plastic deformation' region of the stress/strain curve. The diagram shows the curve for a uniaxial sample tested along ...

Engineers have long used stress-strain curves to uncover a host of material properties. The curves are created by plotting the results of tensile strength tests of material samples, putting stress ...
