Modulus of Rigidity

Sponsored Links

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)
