Abstract
During the past 25 vears the optical method of caustics has matured to a very powerful tool for application in fracture mechanics for the determination of stress intensity factors or the J-integral, in contact mechanics for the determination of contact forces etc. The technique is applicable to two-dimensional static or dynamic problems and works for any kind of stress-strain relationship. The method displays its full power when employed in conjunction with interactive numerical data reduction and evaluation procedures. Recently, the industrial application of high strength-low weight composite materials has boomed. Application of the method of caustics to anisotropic materials requires the development of the theoretical background. This contribution focuses on the theoretical development of the method of caustics and its applicability to anisotropic materials.
