Modulus of shear G  Shear strength, Tensile strength ...
Material G [GPa] The maximum shear stress of ductile materials (steels) is usually taken 0.58 times the Ultimate Tensile Stress (τ = 0.58 UTS) according von Mises failure criterion (distortion energy criterion). For brittle materials the ultimate tensile stress is taken for the maximum shear stress (τ = UTS).
