摘要：
The ultrasonic longitudinal guided waves in oblique defected pipes were investigated using finite element software LS-DYNA in this paper. A novel inspection method was proposed based on the Van der Pol oscillator. Five kinds of defects with inclined angle of 0 degrees, 30 degrees, 45 degrees, 60 degrees and 90 degrees were analyzed, respectively. Numerical results show that the proposed method could be used to inspect weaker guided waves, and the amplitude of echo increases with the decrease of the inclined angle. The results are worthy of engineering application in both extending guided waves detection range and increasing the sensitivity of detecting micro oblique defect.
