Shear Properties.—The properties of shear yield strength, Ssy, shear ultimate strength,
Ssu, and the modulus of rigidity, G, are determined by direct shear and torsional tests. The
modulus of rigidity is also known as the modulus of elasticity in shear. It is the ratio of the
shear stress, τ, to the shear strain, γ, in radians, within the proportional limit: G = τ/γ. |
