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:

λ (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
