A fast integral equation model for the eddy-current signal calculation of thin cracks breaking the wall of a borehole in a conducting plate is presented. The model is based on the surface integral equation formalism using a dedicated Green’s function, which takes into account the effect of the borehole. The approach followed for the construction of the Green’s kernel and the primary field is the Truncated Region Eigenfunction Expansion (TREE) method.
