The aim of this project is to investigate the performance of GWT on corrosion quantification in pipes. This requires developing advanced numerical algorithms consisting of: (1) an efficient forward solution for describing guided waves in thin-walled structures; (2) an inverse solution for the reconstruction of waveguide parameters; and (3) optimization procedures to link inversion parameters with monitored structural parameters. Finite element simulations on models of different types of damage are required to generate the input data for the tomography, with an aim to verify the detection, localization and sizing capabilities of the algorithm. o improve the fidelity and assess the accuracy of the modelling results, experimental validations on selected artificial and real damages in plates and pipes are needed. Such experiments require advanced experimental set-up (multi-sensor system) with novel signal processing techniques.
