1. Direct Calculation of Wave-Induced Loads and Fatigue Damage of Container Vessels
Sammanfattning : Container ships and their rules for fatigue design are in several ways differentcompared with other types of commercial ships such as tankers and bulk carriers. Forexample, most modern container ships have a pronounced bow flare and an overhangstern. LÄS MER
2. Very high cycle fatigue of automotive steels : Testing and computation at 20 kHz
Sammanfattning : 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. LÄS MER
3. On some Fatigue Problems Related to Steel Bridges
Sammanfattning : This thesis concerns three specific fatigue topics related to steel members in bridges, namely: (1) Modular Bridge Expansion Joints (MBEJs). Several premature fatigue failures of MBEJs have occurred in Europe and USA during the past decades. LÄS MER
4. Fatigue Assessment of Friction Stir Welded Joints in Aluminium Profiles
Sammanfattning : Friction stir welding (FSW) is a low heat input solid state welding technology. It is often used for fabrication of aluminium alloys in transportation applications including railway, shipbuilding, bridge structures and automotive components. LÄS MER
5. Mechanical properties and microstructure of laser sintered and starch consolidated iron-based powders
Sammanfattning : In powder metallurgy research field, Direct Metal Laser Sintering (DMLS) and Metal Powder Starch Consolidation (MPSC) are relatively new rapid forming techniques to fabricate complex and near net-shaped components. The working principles of DMLS are to melt and fuse metal powder layer by layer in computer controlled systems to pile up components like three dimensional printing. LÄS MER
