本文通过实验和数值模拟研究了利用Lamb波中的A0模检测碳纤维增强塑料（CFRP）层合梁脱层位置的可能性。发展了一种激发和检测纯A0模的实验技术.通过测量A0模的传播速度和从脱层反射的信号的行进时间，可以通过实验和数值方法来识别脱层的位置。此外，数值分析已被扩展，以获得更好的理解之间的复杂的相互作用A0模式和一个长的脱层情况。
In this study, experimental and numerical investigations have been conducted to explore the possibility of using A 0 mode in Lamb waves to detect the position of delamination in carbon fiber reinforced plastic (CFRP) laminated beams. An experimental technique for exciting and sensing the pure A 0 mode has been developed. By measuring the propagation speed of A 0 mode and traveling time of a signal reflected from the delamination, its location can be identified experimentally and numerically. Moreover, the numerical analysis has been extended to gain a better understanding of the complex interaction between A 0 mode and a long delamination case.
