12. Estimating inclusion content in high performance steels
Sammanfattning : Non-metallic inclusions in steel pose a major problem for the fatigue resistance, especially regarding fatigue at very long lives corresponding to low cyclic stress levels, as well as being detrimental to material toughness and polishability.The largest inclusions are quite rare, which makes conventional detection methods timeconsuming if reliable results are to be obtained.

13. Thermal Barrier Coatings : Durability Assessment and Life Prediction
Sammanfattning : Thermal barrier coating (TBC) systems are coating systems containing a metallic bond coat and a ceramic top coat. TBCs are used in gas turbines for thermal insulation and oxidation resistance. LÄS MER
14. Physically Based Engineering Models for NCF Composites
Sammanfattning : Non-Crimp Fabrics - NCF – are increasingly being used as reinforcements in high performance composite materials. NCF offer the manufacturing advantages from textile preforms in combination with excellent mechanical performance. This study concerns the mechanical performance of NCF composites. LÄS MER
15. Wrinkling of sandwich panels for marine applications
Sammanfattning : The recent development in the marine industry with largerships built in sandwich construction and also the use of moreadvanced materials has enforced improvements of design criteriaregarding wrinkling. The commonly used Hoffs formula isnot suited for the highly anisotropic fibre reinforced sandwichface sheets of today. LÄS MER
