Elastic modulus - Wikipedia

An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. The elastic modulus of an object is defined as the slope of its stress–strain curve in the elastic deformation region: A stiffer material will have a higher elastic modulus.

The modulus of elasticity is calculated by assuming different values of Poisson's ratio. The study reveals that, modulus of elasticity is in the range of 22 to 25 MPa, which reasonably falls in the range given in different literature. The studied range of Poisson's ratio is not significantly influencing the Modulus of Elasticity of sand.

Young's modulus - Wikipedia

Young's modulus or Young modulus is a mechanical property that measures the stiffness of a solid material. It defines the relationship between stress (force per unit area) and strain (proportional deformation) in a material in the linear elasticity regime of a uniaxial deformation.. Young's modulus is named after the 19th-century British scientist Thomas Young.
