Course contents
Students will gain an in-depth understanding of the complex material damage, strength and lifetime of samples and components subject to varying mechanical stresses. Students will have an understanding of the cause and appearance of fatigue fractures, the basic processes underlying material fatigue, the lifetime and fatigue strength of metallic materials, the effect of the surface, lifetime prediction, material reliability, fracture mechanics, fracture phenomena and mechanisms, crack behaviour in materials and components, as well as the safety and risk assessment of structures potentially containing cracks.
- Experimental methods for determining material fatigue
- Phenomenological description of strain cycling behaviour
- Lifetime prediction concepts
- Microstructural fracture formation mechanisms
- Complex operating stresses
- Foundations of linear elastic fracture mechanics
- Concepts for describing fatigue crack growth
- Short fatigue crack growth and crack closure mechanisms
- Vibration resistance of welds
- Thermal-mechanical fatigue
- Special features of the fatigue behaviour of individual material groups
