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.
Course description for study year 2022-2023
Semester tution start
Number of semesters
Language of instruction
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.
