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 ...

Durability of components under dynamic load can be increased by understanding the origin of the stress and strain distribution. While numerical simulations based on finite element (FE) models can help ...

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 ...

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 ...
