Relationship between Modulus of Elasticity (E) and Bulk Modulus (K)
E: Modulus of Elasticity: K: Bulk Modulus; μ: poisson’s ratio
here, the bulk modulus (K) is the ratio between the normal stress and the volumetric strain.
The modulus of elasticity is the ratio between normal stress and normal strain.
Poisson’s ratio is the ratio between the lateral strain and the linear strain and is said to be a constant for a given material.
