  1. 6. Mechanical properties of stainless steel clinched joints

    Författare :Per Sjöström; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Clinching is a joining method for sheet material where the joint is created without need of heat or additional material. The material is joined by local plastic deformation creating a geometrical locking. Since the materi al is not heated during joining, problems caused by HAZ or phase transformation during heating or cooling can be avoided. LÄS MER

  3. 7. Non-Linear Vibration and Dynamic Fracture Mechanics of Bridge Cables

    Författare :Armando Leon; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cable Vibrations; Non-Linear Vibration; Dynamic Fracture Mechanics; Cable-Stayed Bridges; Dynamic Stress Intensity Factor;

    Sammanfattning : In the present work, the non-linear vibrations and the corresponding dynamic fracture mechanics of cables of cable-stayed bridges are studied. The cables are among the most critical components in cable-stayed bridges and there are different damage sources such as corrosion, vibration, fatigue and fretting fatigue that can significantly affect them, thereby reducing the cable’s service life and even producing their failure.
