Explanation

Young's modulus measures tensile stiffness, bulk modulus relates to volumetric compression, shear modulus describes resistance to shear deformation, and elastic modulus is a general term for material stiffness. The ratio of lateral strain to axial strain within the elastic range is specifically called Poisson's ratio.
