Photoelasticity technique allows us to analyze pressures in any system from single to complex geometries. A team called polariscopic, a beam of polarizad light passing through a photoelastic model, forms the physical principie that allows us to perform this analysis. This model is subjected to externa! loads; by the action of the light beam bands of different colors can be observad, wherein each color defines a stress level. For our case, a small beam subject to bending loads is analyzed; a model based on gelatin, glycerin and water was used, which has yielded good results in terms of the appreciation of color bands.
