摘要
本文阐述焦散线法测定复合型裂纹应力强度因子的基本原理,分析常用的测量方法,提出了焦散线的多点测量法,从而改进了P.S.Theocaris提出的经典方法,并以实验进行了验证。
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.
