Abstract

In this paper, a technique for the detection and the sizing of cracks on isotropic plate structures is presented. The generation and the reception of the detection signals-Lamb waves-are made possible by piezoelectric transducers. The presence and the length of cracks are found by the method of triangulation using signals scattered by crack tips. The practicability of the technique is then assessed by a numerical experiment.
