  3. 2. Fatigue Assessment of Cast Components : Influence of Cast Defects

    Författare :Anders Björkblad; Jack Samuelsson; Gary Marquis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cast nodular iron; fatigue; design rules; fracture mechanics; Vehicle engineering; Farkostteknik;

    Sammanfattning :  This thesis is on the fatigue assessment of cast components with special attention to defects. The primary material in view is nodular cast iron, but also cast steel is considered. However, the fatigue behaviour is in principle valid for general use on other cast metals. LÄS MER

    Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER
