Description

The reflected shadow method of caustics was applited up to now for the study of the stress fields around isolated cracks [1]. In this paper the theory is extended to the general case of an array of collinear asymmetric internal cracks. A rigorous analysis of the interaction between neighboring cracks is developed and the influence of the intererack distance, as related to the size of neighboring cracks, is determined. It is shown that the shape and size of the caustic are dependent on the abovementioned factors. Since the dimensions of the caustic are directly related to the complex stress intensity factor, K*, it is shown that the method is effective in accurately determining the instantaneous value of K*. © 1973 Springer-Verlag.
