Material fatigue and reliability

Content of the course

Students have in-depth knowledge in the field of complex material damage, strength and service life of specimens and components under changing mechanical loads. They are able to understand the cause and manifestation of fatigue fractures, the basic processes involved in material fatigue, service life and fatigue strength of metallic materials, the influence of the surface, service life prediction, material reliability, fracture mechanics, fracture phenomena and mechanisms, crack behavior in materials and components as well as the safety and risk assessment of potentially cracked structures.

• Experimental methods of material fatigue
• Phenomenological description of the fatigue deformation behavior
• Concepts for service life prediction
• Microstructural crack formation mechanisms
• Complex operational stresses
• Fundamentals of linear-elastic fracture mechanics
• Concepts for the description of fatigue crack growth
• Short crack growth and crack closure mechanisms
• Fatigue strength of welded joints
• Thermo-mechanical fatigue
• Special features of the fatigue behavior of individual material groups
