Semi-brittle deformation in geologic systems is generally defined micromechanically 5,6,7, wherein fracturing and/or frictional sliding characterizes the deformation of one mineral phase while ...

If the material has no capacity for work-hardening, then the stress-strain curve is flat beyond the yield point (F = 0). In summary, such materials are mechanically described by only four parameters: ...

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 ...

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 ...

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 ...

Elastic Modulus 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 ...

With a simple sample geometry, a 3-point-bend test can be used to obtain stress-strain behavior, elastic modulus in bending (flexural modulus), and failure limits in bending. The standards ASTM E855, ...
