Modulus of rigidity or shear modulus is the rate of change of unit shear stress with respect to unit shear strain for
the condition of pure shear within the proportional limit. Modulus of rigidity
formula is G = E/(2(1+v)), and modulus of rigidity is G, elastic modulus is E and Poisson's ratio is v in the formula. Modulus of rigidity value of a material is determined
by a torsion test.
Typical values of modulus of rigidity: Aluminum 6061-T6: 24 GPa, Structural Steel: 79.3 GPa.
Modulus of rigidity calculator has been developed to calculate modulus of rigidity of a material with modulus of elasticity and Poisson's ratio values. This calculator is valid for a
linear, homogeneous, isotropic material. The formulas used for calculation are given in the "List of Equations"
section.
