Abstract
In this paper a method is presented for an efficient solution of the direct problem (find the scattered field for a given thin crack and driving field ) in the time domain. This is a fundamental step in any non destructive eva luation problem. Two different approaches, one in the time domain and the o ther based on Fourier analysis, are used and compared with reference to a c onfiguration for which some experimental results are available. The advanta ges and drawbacks of the two approaches ave briefly discussed.
