Curvature to stress
Webcurvature can be obtained by measuring the bow and deflection of the substrate. By comparing the change in radius of curvature before and after film deposition, it is then possible to estimate the stress using the cantilever beam technique developed by G. Gerald Stoney for thin film stress measurements2: 𝜎𝜎= 1 6𝑅𝑅 𝐸𝐸 (1− ... WebJul 6, 2024 · R = radius of curvature of the neutral θ = angle subtended by the beam length at O. σ = longitudinal stress EF = E'F ' since, EF is a neutral axis As we know, Angle = Arc/Radius So, in ∠OE'F' θ = E'F '/R E'F ' = Rθ Clearly shown in the figure, EF = GH = E'F' = Rθ Again in ∠OG'H' θ = G'H'/ (R+y) G'H' = (R+y)θ Now, Strain in GH
