摘要：

Different nondestructive crack inspection approaches have been previously proposed for a wide range of industrial applications. Among those approaches, field measurement resulting from impressed current crack perturbation has been suggested. In this paper, semi-orthogonal compactly supported spline wavelets are used to efficiently identify the 3D spatial location of embedded cracks in conducting slabs of finite thicknesses. Within the proposed approach a couple of oppositely arranged field sensor pairs are employed on top and bottom of the conducting slab under consideration. Details of the crack detection methodologies and simulations are given in the paper.
