Elastic modulus is sometimes called Young's modulus after Thomas Young who published the concept back in 1807. An elastic modulus (E) can be determined for any solid material and represents a constant ratio of stress and strain (a stiffness):. A material is elastic if it is able to return to its original shape or size immediately after being stretched or squeezed.
