2011-3-11 2. ON DEFORMATION AND ELASTIC MODULI 2.1 Definitions Deformability is characterized by a modulus describing the relationship between the applied load and the resulting strain. The fact that jointed rock masses do not behave elastically has prompted the usage of the term modulus of deformation rather than modulus of elasticity or Young's modulus.
