Abstract

In the fields of mechanics and materials science, photoelasticity is a reliable experimental method that provides a visual evaluation and analysis of the distribution of stress in materials that are transparent or translucent. This non-destructive testing technique uses the special property of materials known as birefringence, or double refraction, to visualise stress on a model under load. The process involves building a physical model that mimics real-world structures, applying mechanical stress to the model, and carefully choosing a suitable photo elastic material that exhibits birefringence. The material undergoes birefringence when it is under stress, which causes changes to its optical characteristics. As a consequence, different stress levels are reflected in the pattern, which makes it easier to identify stress concentrations and possible failure areas and offers insights into how materials behave under varied circumstances. In the current study, a photoelasticity unit was used to evaluate the compact circular specimen under four different stresses. Next, a comparison was made between the experimental analysis’s results and those from the ANSYS simulation

Keywords: Polarization, Photo elasticity, Polari Scope, Stress, Isochromatic and Isoclinic Fringes.
