Most papers in the literature treat the analysis of delamination test methods by use of elementary strength of materials models. Since most of the specimens physically resemble beams, beam theory is often applied. While the approach is valid within a fairly wide range of parameters, for cases whe...
IECTS62804-1-1:2020ENPhotovoltaic(PV)modules-Testmethodsforthedetectionofpotential-induceddegradation-Part1-1:Crystallinesilicon-Delamination是一个关于光伏(PV)模块的测试方法标准,旨在检测由于电位诱导退化(PIED)引起的潜在问题。这个标准特别关注了晶体硅(Crystallinesilicon)组件中存在的分离层(Delamination)现象。
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 ...
There are national and international standard test methods for the determination of the mode I strain energy release rate for unidirectional laminates, where the delamination is constrained to move in the fibre direction. In real components, made up of multidirectional plies, there is no reason to ...

Three tests are conducted to compare the accuracy and effectiveness of the two methods: DCB, ENF and MMB. The loading and boundary conditions are presented in Fig. 2 and the set-up parameters for each test investigated are presented in Table 1. The simulated specimen consists of two parts, ...
Commercial maritime interests and the Navy are keenly interested in designing and utilizing hardware that is as resistant to cathodic delamination as possible. One of the most commonly employed methods for determining cathodic delamination resistance is the saltwater accelerated life test (ALT). Such a...
