Impedance of an Induction Coil Accounting for the End-Effect in Eddy-Current Inspection of Steam Generator Tubes

摘要

A fast model for the eddy-current signal calculation of thin cracks at the vicinity of a conducting tube edge is presented. The model is based on the surface integral equation formalism using a dedicated Green's function. The approach followed for the construction of the Green's kernel and the primary field is the Truncated Region Eigenfunction Expansion (TREE) method.
