In an isotropic elastic solid, Young's modulus, Poisson's ratio and the shear modulus are not independent of one another. You can see this by applying a shear stress (see diagram below) then rotating the coordinates by 45 (by performing the tensor transformation) about the z-axis to get the corresponding normal components of stress, evaluating the corresponding normal components of strain and then returning back to the original coordinate system. E Derive G = using this tensor transformation procedure described 2(1+v) above. Upload Choose a File X
