This video by ADMET shows a concrete compression test performed according to ASTM C469 - Standard Test Method for Static Modulus of Elasticity and Poisson's Ratio of Concrete in Compression.

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 ...

A study compared various artifical intelligence techniques for determining Poisson's ratio and Young's modulus. These techniques provide an alternative, less costly method for determining mechanical ...

If the Poisson’s ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

Nanoindentation is a method of measurement of the mechanical properties of small volumes of materials using an instrumented indentation technique. Elastic modulus, hardness, fracture toughness, creep ...

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 ...

Subjecting a material to a hydrostatic stress also causes elastic deformation. The stress is the pressure, p, acting on the body and the strain, d = DV/V. These quantities are related through a ...
