Fatigue and fracture (BYG540)
The course aims to impart an understanding of structural integrity and its main themes of material properties, applied stress and defects or cracks. The underlying science of fracture mechanics is fundamental to the course and the practical application of these concepts to structures is also covered, as are fatigue; welding; welding defects and non-destructive testing.

Content
Central topics are welding flaws, degradation mechanisms, inspection, condition assessment, failure analysis. Specific topics are: linear elastic fracture mechanics, elastic-plastic fracture mechanics, fracture mechanics testing, fatique, crack growth, failure assessment diagrams, BS7910 and R6 methods, non-destructive examination. Some work on finite element analysis.

Course assessment
There must be an early dialogue between the course supervisor, the student union representative and the students. The purpose is feedback from the students for changes and adjustments in the course for the current semester.In addition, a digital subject evaluation must be carried out at least every three years. Its purpose is to gather the students experiences with the course.
