Investigation of Non-equibiaxial Thin Film Stress by Using Stoney Formula
TL;DR: In this paper, the Stoney formula was used to determine the thin film stress and the radii of curvature of circular disks made of PSM-1 photoelastic material and coated with the silicon dioxide (SiO2) thin film of different thicknesses.

An Automated Phase Unwrapping Algorithm for Isoclinic Parameter in Phase-Shifting Photoelasticity
Pichet Pinit,Eisaku Umezaki +1 more
TL;DR: In this paper, an automated phase unwrapping algorithm for the isotropic point in the true phase interval (π)/2 to π/2) is presented. But this algorithm is combined with a four-step colour phase shifting technique.
