Abstract

Eddy current testing (ECT) probe signal due to cracks can be predicted by separating the calculation steps to the evaluation of the incident field and the reaction of the crack. Finite element (FEM) and boundary integral (BIM) methods can be, for example, advantageously applied for the calculation of the incident and reaction fields, respectively. The computational environment presented in this paper allows the blending of the different calculation methods for the purpose of ECT probe signal calculation. As a result, a fast and versatile tool is obtained to calculate the signal of complicated ECT probes due to cracks. The developed approach is validated through comparisons with experimental data
