Abstract
In thick-walled pipe, lamination defect is one type of commonly appeared defects in the manufacturing process. This paper presents a quantitative detection method of lamination defect in thick-walled metallic pipe using circumferential Lamb waves based on wavenumber analysis algorithm. A 3D finite element model is established, and an experimental study is performed with the same setting as the numerical study. Both the numerical result and experimental result are consistent with each other. The reconstructed values show that the lamination is located near the outer surface at nearly about 2.3 mm, which gives a relative error of 15%.
