rock - Mechanical properties | Britannica

rock - rock - Mechanical properties: When a stress σ (force per unit area) is applied to a material such as rock, the material experiences a change in dimension, volume, or shape. This change, or deformation, is called strain (ε). Stresses can be axial—e.g., directional tension or simple compression—or shear (tangential), or all-sided (e.g., hydrostatic compression).

Stress – Strain Relationships

E ⇒ Modulus of Elasticity - Slope of the initial linear portion of the stress-strain diagram. The modulus of elasticity may also be characterized as the "stiffness" or ability of a material to resist deformation within the linear range. E (Steel) ≈ 30 x 106 psi E (Aluminum) ≈ 10 x 106 psi E
