The investigation about the significant effects of stress raisers demands well-defined evaluation techniques to accurately determine the stress on the geometric boundary. While various measuring tools are available, the hybrid method employing the least-squares method integrated with Laurent series representation of the stress function was used to estimate dependable stresses around the circular hole in a tensile-loaded plate out of experimental x-displacement data away from the boundary. Traction-free conditions were satisfied at the geometric discontinuity using conformal mapping and analytic continuation. Results from this approach were closely comparable with those of FEM.
