1. Multi-axial fatigue of welded details
Sammanfattning : Welds and welded joints are nowadays very common in steel structures. Since thewelded parts also are susceptible to fatigue, they can have a major influence on thetotal life of the structure. LÄS MER
2. Influences of temperature, fatigue and mixed mode loading on the cohesive properties of adhesive layers
Sammanfattning : This thesis concerns some aspects that have influence on the strength of adhesive layers. The strength is determined by the stress deformation-relation of the layer. This relation is also referred to as cohesive law. LÄS MER
3. Finite element procedures for crack path prediction in multi-axial fatigue
Sammanfattning : Rolling Contact Fatigue (RCF) cracks in rails are among the most detrimental railway track defects regarding reliability and cost. The cracks typically grow in shear mode up to a certain length at which they might arrest or kink into a more tensile-driven growth. LÄS MER
4. Wheels, Rails and Insulated Joints - Damage and Failure Probability at High Speed and Axle Load
Sammanfattning : The thesis deals with some fatigue related problems in railway mechanics related to increased axle loads and speeds. The focus is on defects and discontinuities in the wheel--rail system that affect the risk of fatigue and fracture of railway components such as wheels, rails and insulated joints. LÄS MER
