Web2. THE PHOTOELASTICITY METHOD The longerons of the chassis support the main loadings which produce plane stress states and plane strain states, respectively, which can be analyses through the photoelasticity method. For this purpose, there have been realised photoelastic models equivalent to the real longeron, at a 1:20 scale of dimensions; WebPhotoelastic stress analysis has long been used to assess the magnitude, direction and distribution of stresses in loaded transparent or translucent components or models.41 Assumptions made in that work are that the strains are small and that the stress optical coefficient relating stress to birefringence is independent of strain.
