Modulus of Rigidity (or Shear Modulus) is the coefficient of elasticity for a shearing force. It is defined as "the ratio of shear stress to the displacement per unit sample length (shear strain)" .

Modulus of Rigidity can be experimentally determined from the slope of a stress-strain curve created during tensile tests conducted on a sample of the material.

Definition of Modulus of Rigidity:

• The ratio of shear stress to the displacement per unit sample length (shear strain)

Modulus of Rigidity of some Common Materials

• 1 GPa = 0.145x10⁶ psi (lb_f/in²)
• 1 x 10⁶ psi = 6.9 GPa
