本研究采用电阻变化方法来监测分层。作者发现，使用响应面的电阻变化方法对于通过实验和分析识别 CFRP 层压板中的分层非常有效。在本研究中，使用有限元分析研究了电极间距对该方法的影响。这里分析了五种类型的间距，并且还计算了两种类型的纤维体积分数。采用交叉层梁型试样进行分析。结果表明，间距的影响取决于纤维体积分数。对于高纤维体积分数的层压板，需要短间距以获得分层位置和长度的高估计性能。
The present study employs an electrical resistance change method for monitoring delamination. The authors have found that the electrical resistance change method using response surfaces is very effective in identify delaminations in CFRP laminates both experimentally and analytically. In the present study, the effect of the spacing between electrodes on the method is investigated using FEM analyses. Five types of spacing are analyzed here, and the two types of fiber volume fractions are also calculated. Cross-ply beam type specimens are adopted for the analyses. As a result, it was revealed that the effect of the spacing depends on the fiber volume fraction. For laminates of high fiber volume fraction, a short spacing is required to obtain high estimation performances of delamination location and length.
