Relationship between E, G and K of a material

E=

(Strength of Materials – by Er. R.K. Rajput)

The above formula gives the relationship between the Modulus of Elasticity (E), Modulus of Rigidity (G) and Bulk Modulus (K)

Modulus of Elasticity (E): it is the ratio between the normal stress and normal strain of a material in N/m^{2}.

Modulus of Rigidity (G): it is the ratio between shear stress and shear strain of a material in N/m^{2}.

Bulk Modulus (K): it is the ratio between the normal stress and volumetric strain of a material in N/m^{2}.
