Modulets indhold, forløb og pædagogik
Students who complete the module:
Læringsmål
Viden
- Have gained a comprehensive understanding of fracture
mechanics.
- Have gained knowledge in applying classical methods in
designing against fatigue fracture by studying notches and their
effect, by studying strainfatigue, and by analysing eigen-stress
states.
- Have gained an understanding of how to apply fracture mechanics
in the assessment of reliability of practical designs and machine
elements.
Færdigheder
- Be able to assess the stability of cracks using Griffith’s and
Irwin’s fracture criteria, energy release rate, and toughness
concepts.
- Be able to apply linear elastic solutions for sharp cracks and
obtain the stress intensity factor.
- Be able to assess mixed mode loading and apply crack growth
direction hypotheses.
- Be able to assess crack growth by fatigue, partial damage and
load spectra.
- Be able to assess crack initiation, notches and their
effect.
- Be able to determine life time and apply methods for improving
the fatigue strength and life time of machine elements and welded
details.
Kompetencer
- Be able to understand and apply linear elastic concepts in
assessing the stability of cracked structures under static and
fatigue loading.
- Be able to distinguish between different fatigue regimes, i.e.
elastic or plastic, and un-cracked or pre-cracked, and apply
correct methodology to each case in relevant structures.
- Be able to determine the lifetime of welded components, and
explain fatigue in welded components on the basis of fracture
mechanical concepts.
