ADAPTIVE MEASUREMENT SYSTEM FOR DETECTING CRACKS IN CONDUCTIVE MATERIALS

Andrea Bernieri, Giovanni Betta, Luigi Ferrigno

Abstract

A measurement station able to carry out reliable non-destructive testing on conductive materials was set up and tested. It is characterised by a high flexibility thanking to suitable user interfaces that allows an easy definition of the scanning and measurement parameters. An adaptive scanning strategy allows a reduction of the investigation time by optimising the scanning step in function of the measured data. Experimental results on a number of specimens with known cracks prove the effectiveness of the realised station.
