Abstract
This paper presents a hybrid database approach for simulation of remote field eddy current testing (RFECT) signals due to a local defect. By calculating databases related to the coils with an axisymmetric 2D code and that due to unit sources by a 3 dimensional FEM analysis, 3D simulation of the RFECT signal due to a local defect is successfully realized by using the database approach developed by authors. The validity of the approach is verified by comparing the signal due to a full-length circumferential defect calculated with the proposed hybrid database approach and the axisymmetric 2D code.
