Summary on Grant Application Form
Non-destructive testing (NDT) is a well established approach for judging the integrity of structures. Guided waves play a strong role in NDT particularly for identifying cracks or defects in industrial applications related to this proposal. Recently, interest has arisen in using NDT to inspect the structural integrity of bars (rock bolts) embedded in a surrounding material (rock), or of curved pipelines. This project brings together the complimentary skills of an applied mathematician and NDT group, that have overlapping interests in elastic wave theory, to tackle the underlying difficulties in this application of guided waves. Our aim is to describe as fully as posible, using numerical (finite element), experimental and semi-analytical methods (ray-theory), the effects of curvature upon guided elastic waves. Simultaneously we aim to utilize this knowledge to enhance NDT software that is currently used by many industrial and academic groups.This project is designed to both meet an industrial need and simultaneously address an interesting mathematical problem.
