    Abstract : During the last decade an alternative to conventional internal combustion engines, i.e. spark-ignited and Diesel engines, has been under investigation by an ever-increasing number of research groups. READ MORE

  5. 8. Lifetime modeling and management of transformers

    Author : Johanna Rosenlind; Rajeev Thottappillill; Zhong Dong Wang; KTH; []
    Keywords : transformers; lifetime modeling; asset management; thermal modeling; lifetime estimation;

    Abstract : This work have studied and developed lifetime estimation methods for the power transformer and how these could be used for asset management purposes. It is researchperformed in the intersection of the fields of reliability theory, statistical analysis, and stochastic process theory applied to lifetime estimations and management of transformers.

  6. 9. Sintering of cemented carbides : experiments and modeling

    Author : Sven Haglund; KTH; []
    Keywords : ;

    Abstract : During sintering of cemented carbides large volumetricshrinkage takes place. About half the volume of the originalgreen body is lost during this process. Due to lotal densitydifferentes within the green body undesired shape changes mayalso occur during sintering. READ MORE

  7. 10. Fatigue crack growth in fiber metal laminates : experiment and modeling

    Author : Per Hofslagare; Michel van Tooren; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Fiber Metal Laminates (FML) is a class of materials with highly resistant fatigue behavior, developed primary for the aerospace industry. The laminates are comprised of alternating layers of high strength aluminwn sheet and fiber reinforced polymers. READ MORE
