Is it for me?
Structural, civil, maintenance, pipeline, materials, welding, inspection and plant engineers including those responsible for maintaining welded equipment and structures, managing the integrity of ageing structures and optimizing asset performance.
Key features of the course: - Introduces the concepts of fitness-for-purpose and engineering critical assessment (ECA), using a mixture of lectures, informal discussion, quizzes, videos and software exercises to reinforce learning
- Focuses on the practical applications of fracture mechanics and covers brittle and ductile fracture, plastic collapse, fatigue crack growth and stress corrosion cracking
- Highlights fracture and fatigue procedures in BS 7910, with an emphasis on how they are applied to welded structures
- Covers a range of relevant subjects related to BS 7910, e.g. failure case studies, non-destructive testing (inspection), materials properties, fracture toughness testing
- Provides practical training in fracture and fatigue assessments using CrackWISE software
- Provides engineers with a firm foundation in the application of BS 7910 to the assessment of flaws using fitness-for-purpose methods
