Lectures

Paul Wilcox on ultrasonic NDT

Paul Wilcox,  Professor of Dynamics, will briefly explain at WEB Workhop I how Non-Destructive Testing (NDT) ensures the safe operation of structures around us. Ultrasonic waves are an essential tool for NDT because they can propagate deep into solid objects. Consequently, ultrasonic NDT is about solving the inverse problem: what information about the interior of an object can be deduced from exterior measurements. Several examples will be presented, including multi-mode imaging, sub-wavelength defect characterisation and non-linear elasticity mapping.
