Abstract—

By the example of a local inhomogeneity in the form of a horizontal crack, a numerical and experimental confirmation of the existence of resonance effects in an inhomogeneous elastic strip, investigated by I. I. Vorovich, is given. Examples of the use of this phenomenon for detecting delamination in composite plates and determining their size and depth based on the data of ultrasonic monitoring by traveling Lamb waves are given.

弹性导波共振检测复合板脱层的方法

摘要-

以水平裂缝形式的局部不均匀性为例，由II Vorovich进行了研究，给出了在不均匀弹性带中存在共振效应的数值和实验确认。给出了使用这种现象检测复合板中的分层并根据行进的Lamb波进行的超声波监测数据确定其尺寸和深度的示例。
