Building fuel efficient automobiles is increasingly important due to the rising cost of energy. One way to improve fuel efficiency is to reduce the overall automobile weight. Weight reductions using steel components are desirable because of easy integration into existing manufacturing systems. Designing components with Advanced High Strength Steels (AHSS) has allowed for material reductions, while maintaining strength requirements. Two Advanced High Strength steel microstructures investigated in this research utilize different strengthening mechanisms to obtain a desired tensile strength grade

Chronic Fatigue Syndrome (CFS) is characterised by severe fatigue, endured for at least six months, together with symptoms including impaired cognitive function, sleep disturbance, and musculoskeletal pain. The pathogenesis is still unknown, resulting in a lack of treatment options and the stigmatization of patients. Both psychological and biological factors have been implicated in the development of CFS. To date, evidence has come largely from cross-sectional studies, and there have been a paucity of longitudinal studies. The aim of this study was to explore interferon-alpha (IFN-α) induced p

This project is concerned with the fatigue response of roller quenched and tempered (RQT50I) steels. Three closely related aspects are considered: (i) the relationship between the microstructure and fatigue properties, (ii) the influence of the environment on fatigue properties, (iii) theoretical modelling of fatigue crack growth. The material used is an RQT501 grade steel. Two steels have been chosen: (A) without Mo and V additions, (B) with Mo and V additions. The second condition is chosen to evaluate the role of these elements, as hydrogen traps, on the resistance to corrosion fatigue crac

Recently there has been increased interest in chronic fatigue syndrome (CFS), a syndrome of nonspecific symptoms and unknown etiology. The relationship between cardiovascular reflex function, fatigue, and depression in CFS was examined. Findings were as follows: First, there was no evidence of abnormal cardiovascular reflex function in the CFS group. Second, the CFS group had significantly higher systolic and diastolic blood pressure than the control group. Third, the CFS group scored higher on psychological measures of depression, fatigue, and confusion than the control group; the control gro

The software developed monitors and tracks eyes for signs of fatigue by measuring PERCLOS. The software developed runs on the workstation and is designed to draw limited computational power, so as to not interfere with the user task.

The global energy consumption is increasing and together with global warming from greenhouse gas emission, create the need for more environmental friendly energy production processes. Higher efficiency of biomass power plants can be achieved by increasing temperature and pressure in the boiler section and this would increase the generation of electricity along with the reduction in emission of greenhouse gases e.g. CO2. The power generation must also be flexible to be able to follow the demands of the energy market, this results in a need for cyclic operating conditions with alternating output

In the combustion zone of industrial- and aero- gas turbines, thermomechanical fatigue (TMF) is the dominant damage mechanism. Thermomechanical fatigue is a coupling of independent creep, fatigue, and oxidation damage mechanisms that interact and accelerate microstructural degradation. A mixture of intergranular cracking due to creep, transgranular cracking due to fatigue, and surface embrittlement due to oxidation is often observed in gas turbine components removed from service. The current maintenance scheme for gas turbines is to remove components from service when any criteria (elongation,

A dented pipe fails either through being punctured or by fatigue damage accumulation due to internal pressure fluctuation. Increasing the wall thickness may prevent these failures but is impractical. As a pipe is punctured, transmission services must be cut off and repair processes have to be made immediately. However, when a dent depth is not large enough to puncture the pipe, the pipe can safely continue in service for a long time until a fatigue crack initiation occurs. Therefore, the fatigue life assessment has attracted much attention in the pipe industries for economic and safety reasons

Plain-fatigue and fretting-fatigue tests have been carried out on the two peak-aged, high-strength aluminium alloys, 7010 and 8090, in the unpeened and shot peened conditions. Shot peening produced a highly deformed surface containing many deep dimples and folds from which fatigue cracks rapidly initiated. Although initiation was early, propagation through the peened surface layers was retarded by the residual compressive stresses introduced by the peening treatment; this retardation being greatest at a depth corresponding to that of the peak residual compressive stress.

Le principal objectif de ce travail de thèse est d'utiliser les critères de fatigue multiaxiale pour dimensionner les assemblages boulonnés. A partir d'une étude comparative des différents critères, nous en avons sélectionné deux : celui de SINES et celui de DANG VAN dont nous avons généralisé la formulation pour prendre en compte le domaine de l'endurance limitée. L'utilisation de ces critères nécessite la détermination de l'état de contrainte au fond du premier filet en prise, lieu privilégié de l'amorçage de la rupture des boulons. Nous avons donc réalisé des modèles éléments finis d'un bou
