Photoelasticity Analysis with Python
Photoelasticity is a technique that uses a polarized light beam on the surface of a birefringent material subjected to a certain mechanical stress to obtain isoclinic fringes. These fringes are correlated with the stress in question, which allows the determination of critical stress points in a material or specimen. Electromagnetic waves incident on anisotropic materials can be divided into two components, due to birefringence and a certain pressure, one of these components is out of phase in time, so that at the output of a certain width of the material, a wave superposition is generated , which generates these fringes with information. Determining the critical points in a material and its load concentrations is important since it makes it possible to improve and generate design alternatives for elements.
