Jun 20 2017 · Young s modulus is defined as "the ratio of stress to strain for uniaxial stress." The modulus of a material is a measure of the stiffness of the material. If the modulus is large the material is stiff. In hydraulic fracturing a stiff rock results in more narrow fractures. If the modulus is low the fractures are wider.
