When performing a photoelastic stress analysis around a stress singularity, such as a concentrated loading point or a crack tip, accurate results of stress analysis usually cannot be expected because of a collapsed image of the fringe due to a steep variation of stress and the insufficient resolving power of ordinary equipments. The function approximation method is a successful and convenient method for compensation of collapsed photoelastic isochromatic data in an extremely condensed area, which has been developed based on a concept of hybrid theoretical and experimental stress analysis. In this study, we determined the opening mode stress intensity factor using the function approximation method in a photoelastic experiment within 3 percent relative error against the theoretical value. The isochromatic image data around a stress singular point were reconstructed.
