It says how easy or difficult is it to elongate some object by applying force. Meaning of Youngs modulus. Youngâs Modulus is a mechanical property of the material where it can be called as modulus of Elasticity/Elastic Modulus. The Youngâs modulus of elasticity is the elastic modulus for tensile and compressive stress in the linear elasticity regime of a uniaxial deformation and is usually assessed by tensile tests.
