Webavoid bending stresses we coated the test-pieces on both sides with equal amounts of birefringent coating (photoelastic coating P.S. 1) employing an adhesive (P.C.6.). The tensile tests were performed in a Hounsfield tensometer. Readings of strain in the plastic-coated region and away from that region were taken both mechanically and optically. map of medley floridaBirefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive). The birefringence is often quantified as the maximum difference between refractive indices exhibited by the material.
