"The Photoelastic Coating Method was applied to find the surface stresses on the cap of an electrical insulator. The strain distribution was observed and photographed. This color photograph indicated a visible geography of the maximum shear strain distribution in the region of the insulator where the birefringent plastic was bonded with a reflective cement. The Oblique Incidence technique was used to determine the principal stresses from the maximum shear strain (or the principal strain difference) readings, obtained from Normal Incidence. The critical cross-section of the insulator head was optically located, giving an initiative for the re-design of the insulator cap. The photoelastic method was applied to determine the state of stress at this critical section"--Abstract, page ii.
