Young's Modulus Formula and Example

Young's modulus is a modulus of elasticity equal to the compressive stress divided by the axial strain. (image: Nicoguaro.

Elasticity and Flexure

In addition, the elastic strain of many rocks is linearly proportional to the appliedstress. The equa-tions of linear elasticity are greatly simplified if the material is isotropic,that is, if its elastic properties are independent of direction. Although some meta-morphic rocks with strong foliations are not strictly isotropic, the isotropic

Bulk Modulus

The bulk modulus measures a substance's elastic resistance to change in volume when under uniform loading in all directions. It can be thought of as an extension of the Youngs Modulus into three dimensions. The formula for bulk modulus is: (1) Where V = initial volume, dP = change in pressure, dV = change in volume.
