16. Very high cycle fatigue of tool steels
Abstract : An increasing number of engineering components are expected to have fatigue life in the range of 107 - 1010 load cycles. Some examples of such components are found in airplanes, automobiles and high speed trains. READ MORE

17. Trapezius muscle fatigue and electromyographic frequency analysis
Abstract : This study, comprising 6 separate articles, is concerned with different validity and reliability aspects of the electromyogram mean power frequency (MPF) as an estimator of localized musele fatigue in the trapezius muscle. A series of new, and partly controversial and problematic findings are reported. READ MORE

18. Fatigue behaviour of a nickel based superalloy
Abstract : This thesis deals with different aspects of fatigue crack propagation in IN718. The ultimate objective of the work is to gain understanding of the fatigue process, from the macroscopic stress-strain relations to microscopic fatigue crack growth mechanisms. READ MORE

19. Fatigue, functional status, health and pulmonary rehabilitation in patients with chronic obstructive pulmonary disease
Abstract : The aim of this thesis was to describe fatigue, functional limitations due to fatigue and health in patients with chronic obstructive pulmonary disease (COPD), as well as to compare patients with individuals from the general population and to test if pulmonary rehabilitation can reduce fatigue and functional limitations, and thus improve health. A further aim was to test the Fatigue Impact Scale (FIS) among patients with COPD. READ MORE

20. Numerical Modelling of Short Fatigue Crack Growth
Abstract : Fatigue implies repeated loading and unloading of a structure, and components subjected to fatigue might experience nucleation of cracks, and subsequent crack propagation. This might lead to catastrophic consequences, such as complete failure of a structure. READ MORE
