Modulus of Rigidity - G - (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.
The definition of Modulus of Rigidity:
- the ratio of shear stress to the displacement per unit sample length (shear strain)
