Webthe elastic properties of the substrate are speciﬁed by E (Young's modulus), and ν (Poisson's ratio). E and ν provide a valid description for elastically isotropic substrates, e.g. polycrystalline steel strips, as used by Stoney in 1909. Today the Stoney equation is still used for relating substrate curvature to ﬁlm stress.
