Paper Abstract

In this study, the authors propose a method for determining not only the secondary principal stress difference, but also its direction, using 3 image data obtained in various of polarization angles of incident light. As an example, a sphere under diametrical compressive load is analyzed to determine both the secondary principal stress difference and their directions, with or without rotation of the principal birefringent axis along the light path. The results show good agreement with theoretical/computed analyses.
