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. Steel Beyond Coal : Socio-Technical Change and the Emergent Politics of Steel Decarbonisation
Sammanfattning : The steel industry is responsible for 8% of all anthropogenic greenhouse gas emissions and is the second largest user of coal after the power sector. The main emission source in steel production is the blast furnace, which converts iron ore and metallurgical coal into pig iron that is then further refined into steel. LÄS MER
3. Steel Making Hunter-Gatherers in Ancient Arctic Europe
Sammanfattning : Based on findings made by Norrbotten County Museum around 2010 in the vicinity of Sangis in Arctic Sweden of advanced iron and steel production in a hunter-gatherer setting dated to the pre-Roman Iron Age (c. 200-50 BC), the aim of the present thesis is twofold. LÄS MER
4. A Study on Structural Cores for Lightweight Steel Sandwiches
Sammanfattning : Lightweight materials and structures are essential building blocks for a future with sustainable transportation and automotive industries. Incorporating lightweight materials and structures in today's vehicles, reduces weight and energy consumption while maintaining, or even improving, necessary mechanical properties and behaviors.
