对含分层损伤层合板的电响应进行了理论分析和实验研究。本研究代表了通过电气测量检测导电层压板中的分层的基础。作为应用的一个例子，一个双悬臂梁（DCB）试样的情况下，被认为是，目的是计算层压板的表面上的一个点的电位，其变化作为分层长度的函数，突出的最有影响力的参数。理论预测的准确性进行了验证，对一些有限元分析，显示出非常令人满意的协议。除此之外，理论预测也通过与来自特设活动的大量实验数据的比较以及使用从文献中获取的数据来验证。在所有情况下，都发现了良好的一致性。
An analytical and experimental study is carried out on the electrical response of a laminate with a delamination. The present study represents a basis for the detection of delaminations in conductive laminates through electrical measurements. As an example of application, the case of a Double Cantilever Beam (DCB) specimen is considered, with the aim to calculate the electric potential of a point on the surface of the laminate, and its variation as a function of the delamination length, highlighting the most influencing parameters.The accuracy of the theoretical predictions is verified against a number of finite element analyses, showing an extremely satisfactory agreement. In addition to this, theoretical predictions are also validated by comparison with a bulk of experimental data coming from an ad-hoc campaign, as well as using data taken from the literature. In all cases a good agreement is found.
