    Why the the elastic modulus(E), shear modulus(G) and Poisson's ratio(v) don't fit into the formula E=2G(1+v)?

      I assume the Elastic Modulus in the isotropic material properties is Young's Modulus (G) so it should have a relation with Shear Modulus and Poisson's ratio as in the equation below:

      E=2G(1+v)

       

      I tried calculating several materials and none of them meets the above equation. I am wondering what Elastic Modulus stands for here? If it is not Young's Modulus, what is it?
