Summary on Grant Application Form |

Most current industrial applications use guided waves essentially as a screening tool, and hence research has been driven by the need to maximise coverage, which has necessarily been achieved at the expense of sensitivity. However, there is a clear need for a high sensitivity guided wave technique that can perform accurate defect sizing while still being deployed some distance away from the inspected region. Such a system would be utilised for inspecting critical regions of a structure to which direct access, and hence inspection by conventional NDE techniques, is not possible. Long range screening operates at low frequencies and uses low order guided wave modes; in order to obtain better resolution and higher sensitivity, it is proposed to use information obtained from multiple higher order guided wave modes at higher frequencies. This is a major step forward in guided wave inspection and requires research on guided wave interaction with defects, taking into account the three dimensional nature of typical flaws, and on array transducer technology in order to produce a practical system that will send and receive the required modes. The information collected from different transmitted mode - received mode combinations will then be combined to estimate the severity of defects. Instrumentation will be produced to enable the system to be tested on industrial specimens in the laboratory and in controlled site trials.
