The objective of this project is to develop Finite Element modelling procedures for simulating the interaction of ultrasound with defects in structures. Currently the capabilities are limited by a maximum model size such that cracks and corrosion defects have to be idealised by very simple shapes. The project will develop two topics to achieve a step improvement in capability: (a) improved non-reflecting model boundaries, enabling a much smaller local region of the structure to be studied; (b) new methods for numerical representation of the defect region, enabling true shapes to be modelled accurately.
