Abstract
Abstract
Guided wave mode and dispersion curve in the circular rod are analyzed, and the time domain waveform of Φ20mm*2m circular rod is analyzed. Though finite element simulation and experiment, the variation law of reflection coefficient of different guided wave modes is analyzed. The L(0,1) is consistent with the change trend of F(1,1) modes for axial and circumferential defects, and the simulation results of L(0,1) modes are consistent with the test results.
