Modulus of elasticity means:

A. Rigidity or stiffness of the material

B. Ability to be stretched with permanent deformation

C. Ductility of a material

D. Malleability of the metal

Correct Answer: Rigidity or stiffness of the material

Description: ELASTIC MODULUS (YOUNG’S MODULUS OR MODULUS OF ELASTICITY) The word stiffness should come to mind upon reading one of these three terms in the dental literature. Elastic modulus describes the relative stiffness or rigidity of a material, which is measured by the slope of the elastic region of the stress-strain graph.
