Question

For a homogeneous isotropic elastic solid having Young's modulus Y, shear modulus G and Poisson ratio ν, which relation is correct?

G1 Physics · Accepted Answer

For an isotropic elastic solid, the standard relation between Young's modulus, shear modulus and Poisson ratio is Y = 2G(1+ν). Another useful relation is Y = 3K(1−2ν). Therefore the correct option is Y = 2G(1+ν). Correct option: C.
