About the course
Aim
The aim of the course is to give the student
- a basic understanding of the effect cracks and cyclic loading may have on the life of a design
- a basic theoretical knowledge in fracture mechanics
- a basic theoretical knowledge in classic fatigue theory (HCF och LCF)
- an insight in Finite Element-based life analysis and its industrial use
- the ability to independently solve not too advanced problems of the above type analytically and by using an FE-program.
- account for the theoretical basis of Fracture Mechanics and basic classic fatigue theory (HCF och LCF)
- solve not too advanced problems of the above type analytically and by using an FE-program
- give an account of how life analysis is used in the modern design process
Content
Basic Fracture Mechanics:
- Stress field-based linear Fracture Mechanics: Stress intensity, fracture tougness.
- Applicability of linear Fracture Mechanics: Crack tip plasticity. Applicability criteria. Experimental determination of fracture toughness
- Thermodynamics: J and G. Stability
- Fatigue crack growth: Paris’ law. Cycle counting
Basic classic fatigue theory:
- Stress based fatigue theory (HCF): Wöhler-diagrams/SN-curves. Mean-stress effect. Haigh-diagram. Linear damage acculmulation rules. Strain based fatigue theory (LCF). Basquin’s and Manson-Coffin's equations. Ramberg-Osgood’s equation. Cyclic plasticity. Neuber’s rule
