  • Study Notes

    • Elastic properties indicate deformational behavior of rocks.
    • Deformation is expressed as percent strain.
    • Young's modulus and Poisson's ratio are used to evaluate deformational behavior of rocks.
    • Young's modulus is the proportionality coefficient between compressive stress and axial strain.
    • The slope of the stress-strain curve is the Young's modulus.
    • Rock is anisotropic, not isotropic.
    • The elastic properties of rock are not the same in all directions.
    • Poisson's ratio is the extension that occurs perpendicular to the direction of loading.
    • Poisson's ratio ranges from 0.10 to 0.50 for different rocks.
    • Poisson's ratio varies depending on the direction of loading.
