Abstract

The method of caustics is a simple optical method mainly used for the determination of stress intensity factors in crack problems under static and dynamic loading. Together with the method of geometric moiré, they are the only two optical methods of experimental mechanics included in this book that are based on geometric optics and not on the phenomena of interference or diffraction of light, as the other optical methods. Besides crack problems, the method can also be used to obtain optical patterns from reflecting surfaces.
