| Abstract: | Based on the fundamental principle of the caustic method for measuring mixed mode crack stress intensity factors, commonly used methods have been analyzed and the over-deterministic method proposed, thus improving the classical method proposed by P. S. Theocaris. An example is given for verification. |
