1. Fatigue of existing steel bridges : Reliability and risk analyses for decision-making
Sammanfattning : Fatigue is one of the primary reasons that limit the service life of steel bridges. Many bridges in Sweden and other countries have progressively approached their anticipated service lives. Since funding and resources are limited, simultaneously replacement or maintenance of bridges is impractical. LÄS MER
2. Fatigue of Heavy-Vehicle Engine Materials : Damage Mechanisms, Laboratory Experiments and Life Estimation
Sammanfattning : Due to increasing demands on sustainability exerted by end-costumers and policy makers, heavyvehicle manufacturers are urged to increase the engine efficiency in order to reduce the exhaust gas emission. However, increasing the efficiency is also associated with an elevated fatigue rate of the materials constituting the engine parts, which consequently reduces the engine service life. LÄS MER
3. Micro-cracking and delaminations of composite laminates under tensile quasi-static and cyclic loading
Sammanfattning : Aerospace industry is devoted to improving the aircraft performance while reducing its weight and limiting the emissions. Part of this objective can be accomplished with the use of high-performance long fibre reinforced polymer laminated composites. LÄS MER
4. Load Modelling for Fatigue Assessment of Vehicles - a Statistical Approach
Sammanfattning : A way of modelling loads in customer usage for fatigue life considerations of vehicles is discussed. The starting point is lateral vehicle loads acting on trucks. Customer usage is described by using road classification. LÄS MER
5. Road profile statistics relevant for vehicle fatigue
Sammanfattning : Road profiles are studied from a vehicle fatigue point of view. A wide range of roads have been measured: from smooth motorways to very rough gravel roads. It is observed that the road profiles consist of irregular sections, which makes the stationary Gaussian model unsuitable (Paper A). LÄS MER
