| Popis: | This paper presents an analytical solution for the change in impedance due to a flaw of rectangular cross-section in the case when the conductivity of the flaw is sufficiently close to the conductivity of the surrounding medium. The solution, which is found by the small perturbation method, is used to compute the impedance change as a function of the parameters of the flaw. An eddy current nondestructive method based on this consideration can detect the presence of such flaws and, in some cases, determine their size. |
