It is well known that the Voigt and Reuss estimates of the effective shear modulus of a polycrystalline aggregate of cubic crystals are, respectively, the upper and lower bounds for this constant (μR ≤ μ ≤ μV ). It is pointed out in this note that the opposite is true for the Lamé constant λ (λV ≤ λ ≤ λR ).
