1. Very high cycle fatigue of high performance steels
Abstract : Many engineering components reach a finite fatigue life well above 109 load cycles. Some examples of such components are found in airplanes, automobiles or high speed trains. For some materials the fatigue failures have lately been found to occur well after 107 load cycles, namely in the Very High Cycle Fatigue (VHCF) range. READ MORE

2. Very high cycle fatigue of automotive steels : Testing and computation at 20 kHz
Abstract : Mechanical fatigue failure occurs in components subjected to cyclic loading. A crack initiates at critical regions in the component and propagates during repeated loading. The expected fatigue life depends on the level, type and frequency of the loading. READ MORE

3. Fatigue in individuals with multiple sclerosis : lived experiences and perceived impact in daily life
Abstract : The overall aim of this thesis was to gain knowledge about experiences of fatigue among individuals diagnosed with MS and to compare these experiences with those of individuals in the general population. Individuals' experiences of fatigue have been approached both inductively and deductively and qualitative and quantitative research methods have been combined. READ MORE

4. Continuous Welded Railway Rails: Residual Stress Analyses, Fatigue Assessments and Experiments
Abstract : Railway rails are today often continuously welded. This type of joint generally requires less maintenance than is needed for the bolted joints. It has also reduced wheel damage and made the ride more comfortable. However, these joints are subject to damage. READ MORE

5. 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
