For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.

Course specific prerequisites

The student should have basic knowledge in strength of materials, equivalent to the basic courses given in the Bachelor programme in  Mechanical Engineering (Maskinteknikprogrammet).


The aim of the course is that the student should understand the mechanisms behind fatigue failures and be able to design and analyse structures and components subjected to various types of fatigue loading. Further, the student should be able to choose suitable fatigue design criteria depending on type of loading and application.

Learning outcomes (after completion of the course the student should be able to)

identify fatigue loading situations for engineering components and structures
choose and apply different (stress based, strain based and fracture mechanics based) approaches to the fatigue design of components and structures, and also understand the limitations of these approaches
master design against fatigue life under multi-axial loading situations
formulate algorithms needed to analyse fatigue life under irregular load histories
understand and describe the physical background to initiation and growth of fatigue cracks in polycrystalline metals
design fatigue loaded welded joints according to European design codes


The course contains the following parts:

Physical background to fatigue crack initiation and growth
Stress based approach to fatigue design
Variable amplitude loading
Fracture mechanics
Fracture mechanics based fatigue crack growth analysis
Plastic deformation
Strain based approach to fatigue design
Multi-axial fatigue analysis
Design codes for fatigue design of welds
Industrial visits to see operational fatigue testing of components and built-up structures


The course includes about 22 lectures, four design assignments (covering stress based, strain based and fracture mechanics based design and multi-axial fatigue analysis) and two industrial visits.

The examination is based on a written exam, grades TH. Further, approved assignments are a requirement to pass the course.
