This module covers principles of operation, application, suitability for types of defect detection, defect characterisation, limitations and technical developments for a range of Non Destructive Evaluation (NDE) inspection techniques including Ultrasonic and Eddy current inspection.
Students will have a practical example and be introduced to the latest applications and developments of NDE through the research activities of the department. The link will be made between NDE and fracture mechanics and lifetime prediction of components. Fracture mechanics will be further developed for ductile and brittle materials, as well as composite materials, Weibull analysis and fatigue.
The aim of the module is to impart knowledge and understanding of the wide variety of NDE techniques used by industry for defect and material characterisation; inspection and analysis of both discrete and distributed defects. The module starts with basic physical concepts, moving on to systems and practices; the advantages and limitations of these techniques; the scientific principles on which the technique is based and ends with current research challenges.
In the second part of the module the use of linear elastic fracture mechanics for calculating the remaining life of an engineering component or structure containing defects of a known size and geometry will be covered together with studying the methods applied to limit fatigue and fracture in metals, ceramics and composite materials.
This module would thus benefit students who wish to pursue a future career in product design, manufacture, or maintenance.
Topics covered in the module include:
Upon completion of this module students will be able to:
