The correlation between the deviation of light rays and the method of caustics is discussed, and the magnitude of this deviation is shown in diagrams. The application of caustics to stress-frozen models is studied. Lastly, the caustics method is used to determine the stress intensity factor of a crack in a rotating disk.
