摘要：

The alternating magnetic flux leakage testing has being applied in the inspection process for detecting cracks on the surface of steel. In order to develop a precise inspection method, the flux and eddy current distribution should be investigated taking account of nonlinearly of steel. The paper describes 3-D numerical analysis and experiment for this testing. The property of leakage flux from the crack of steel under ac excitation is investigated using 3-D edge-based hexahedral finite element method. The characteristic of leakage flux is confirmed by verification experiment.
