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.
