Abstract

Bolts are widely used in water conservancy and hydropower engineering. There are no good methods to test the corrosion defect of the bolts. Guided wave was used in this paper to test the simulation axial defect in bolt based on FEM. The trend of the axial corrosion coefficient and reflection coefficient of the guided wave was revelled. It shows that the change trend of the defect reflection and wave type conversion of L (0, 1) mode and F (1, 1) mode is consistent. The defect reflection of F (1, 1) is higher than the defect reflection of L (0, 1), both the defect reflection of F (1, 1) and L (0, 1) are no higher than 25%. And also it verified the capability of low-frequency guided wave in detecting the small and medium defects of bolts’ corrosion.
