In solid mechanics, the shear modulus or modulus of rigidity, denoted by G, or sometimes S or μ, is a measure of the elastic shear stiffness of a material and is defined as the ratio of shear stress to shear strain: where is the shear stress, is the shear strain, is the force, is the area, is the traverse displacement, is the initial length or height.
