摘要
根据低频电磁场在导体中的趋肤效应及基准模型中激励线圈相对较小的特点,将轴对称场与三维场相结合。
According to the conductor′s skin effect in low frequency electromagnetic field and the characteristic of comparatively small excitement coil in the benchmark model for eddy current testing, a perturbation model is proposed by combining the axisymmetric field and the 3 dimensional field, in which the disturbed field due to crack in the conductor allows being solved.
