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.
Modulus of Elasticity also know as Young's Modulus is the mathematical description of an object or substance's tendency to be deformed elastically (i.e., non-permanently) when a force 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:
Where:
位 (lambda) = Elastic Modulus
stress = Restoring force caused due to the deformation divided by the area to which the force is applied
strain = Ratio of the change caused by the stress to the original state of the object
