本文主要研究复合材料的纯Ⅲ型脱层行为。综述了纯Ⅲ型分层试验方法的发展。模式III实验的两种测试方法进行了评估：在我们以前的研究中提出的一种新的测试，称为边缘环裂纹扭转（ERCT）测试，和广泛使用的边缘裂纹扭转（ECT）测试。通过实验和有限元分析对两种方法进行了比较。结果显示了ERCT的优势。ECT测试的局限性进行了讨论。
This paper focuses on the characterization of pure mode III delamination behavior of composite materials. The development for pure mode III delamination testing methods is reviewed. Two testing methods for mode III experiments were evaluated: a novel test proposed in our previous study, termed Edge Ring Crack Torsion (ERCT) test, and the widely used Edge Crack Torsion (ECT) test. The two methods were compared by experiment and finite element analysis. The results demonstrate the advantage of ERCT. The limitations of the ECT test are discussed.
