Abstract
The finite-element modeling of thin cracks in eddy-current testing (ECT) using a-psi and t-phi combined vector-scalar potential formulations is presented with edge and nodal Whitney element discretization. The crack is treated as a nonconductive surface on which appropriate conditions are applied. Several benchmark problems have been solved
