Birefringent coating stresses and strains
WebA transparent isotropic solid becomes birefringent when subjected to mechanical force.1 If the solid acts like a uniaxial crystal, the two privileged directions of the crystal at any point of the solid are parallel to the directions of the principal stresses in the plane of the wavefront at that point.

WebFor plane stress in elastic bodies, accuracy of stress or strain determinations along free boundaries is almost entirely independent of coating thickness; however, where Poisson's ratios of coating and structure are unequal, the state of stress in the structure might be influenced by the presence of the coating.
WebOct 29, 2008 · Using a birefringent coating technique, stress separation is carried out on a tooth of a timing belt by two approaches to the shear difference method. The analysis is … WebAbstract The application of birefringent coatings to plane-stress problems associated with orthotropic-glassreinforced plastic materials is treated. The improvement in the sensitivity of the birefringent-coating method due to the high strength and low modulus of the glassfiber-reinforced plastic materials is noted.
Birefringence is used in many optical devices. Liquid-crystal displays, the most common sort of flat-panel display, cause their pixels to become lighter or darker through rotation of the polarization (circular birefringence) of linearly polarized light as viewed through a sheet polarizer at the screen's surface. Similarly, light modulators modulate the intensity of light through electrically induced birefringe…
