Photo Elastic Apparatus

The term "photoelasticity" refers to variations in a material's optical characteristics caused by mechanical deformation. It is a characteristic of all dielectric media and is frequently used to empirically ascertain the stress distribution in a material, providing an image of stress distributions close to discontinuities in materials. For identifying essential stress locations in a material and for locating stress concentration in irregular geometries, photo elastic tests, also known as photoelasticity, are crucial tools.
