G = E/2(1+u) where G = mod of rigidity and u =poisson ration and E = young modulus
well the relation is i don't know .dam i thought i know
It is around 40 GPa.
there are different types of modulus it depends on what types of stress is acting on the material if its direct stress then then there is modulus of elasticity,if tis shear stress then its modulus of rigidity and when its volumetric stress it is bulk modulus and so on
E=3k(1-2/m)

modulus of elasticity = 15 Msi; poisson ratio = 0.3 modulus of rigidity = E/ ((2(1 + poisson)) = 5.8 Msi
The rigidity modulus, also known as the shear modulus, is a material property that measures its response to shear stress. It is independent of the dimensions of the wire, such as its radius. Therefore, if the radius of the wire is doubled, the rigidity modulus remains unchanged. The deformation behavior of the wire may change due to the increased cross-sectional area, but the rigidity modulus itself is a constant for that material.
The elastic modulus, also called Young's modulus, is identical to the tensile modulus. It relates stress to strain when loaded in tension.

The ratio between stress and strain is called the modulus of elasticity or Young's modulus. It represents the stiffness or rigidity of a material and is a measure of how much a material deforms under stress.
The modulus of rigidity of a wire is a measure of its resistance to shearing deformation. It is typically represented by the symbol G and is expressed in units of pascals (Pa). The specific value of the modulus of rigidity for a given wire will depend on its material composition and properties.
Modulus of rupture > Splitting strength > Direct tensile strength
