Abstract

In this study, the interaction between nonlinear ultrasonic guided waves and micro-cracking in pipelines was simulated using finite element method (FEM). The numerical results indicate that after interacting with a micro-crack, the second or higher order harmonics were caused by nonlinear acoustic effects at the micro-crack. The dynamic responses of the pipe with and without a crack were studied in the time domain and frequency domain, respectively. A series of crack sizes were simulated to investigate the sensitivity of the proposed method. In addition, besides the ultrasonic guided waves, low-frequency vibration was simultaneously applied on the pipe with a micro-crack, the simulation results show that the low-frequency vibration could strengthen the higher harmonics, and that its function with respect to cracking identification was highlighted. The numerical results will provide a valuable guide for the application of nonlinear ultrasonic techniques for micro-damage detection in pipelines
