"Photoelastic experiments (also informally referred to as photoelasticity) are an important tool for determining critical stress points in a material, and are used for determining stress concentration in irregular geometries. See more Photoelasticity describes changes in the optical properties of a material under mechanical deformation. It is a property of all dielectric media and is often used to experimentally determine the stress distribution in … See more Photoelasticity has been used for a variety of stress analyses and even for routine use in design, particularly before the advent of numerical … See more The experimental procedure relies on the property of birefringence, as exhibited by certain transparent materials. Birefringence is a … See more Photoelasticity can describe both three-dimensional and two-dimensional states of stress. However, examining photoelasticity in three-dimensional systems is more … See more The photoelastic phenomenon was first discovered by the Scottish physicist David Brewster, who immediately recognized it as stress-induced birefringence. That diagnosis was … See more Isoclinics are the loci of the points in the specimen along which the principal stresses are in the same direction. Isochromatics are … See more The setup consists of two linear polarizers and a light source. The light source can either emit monochromatic light or white light depending … See more " - Photoelastic
