【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.更多还原
