    Abstract : Reduced weight and fuel consumption, improved reliability and engine performance are the main requirements in the automotive industry of today. These requirements demand robust and optimized bolted joints, where a high amount of preload obtained by effective utilisation of the bolt is essential. READ MORE

  2. 2. Joining of Carbon Fibre Reinforced Plastics for Automotive Applications

    Author : Gordon Kelly; KTH; []
    Keywords : Composite; laminate; bearing strength; joining; load introduction; hybrid joint; finite element analysis; mechanical testing;

    Abstract : The introduction of carbon-fibre reinforced plastics in loadbearing automotive structures provides a great potential toreduce vehicle weight and fuel consumption. To enable themanufacture and assembly of composite structural parts,reliable and cost-effective joining technologies must bedeveloped. READ MORE

  3. 3. Dynamic fail-safe behaviour of steel structures

    Author : Ulf Arne Girhammar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The fundamental behaviour and the capacity of steel structures subjected to loss of interior load-bearing elements are studied. The ultimate load-bearing and deformation capacity of certain beam-to-column connections and the dynamic fail-safe behaviour of some ordinary steel structures are investigated in detail. READ MORE

  4. 4. Stiffness of reverse channel connections at room and elevated temperatures

    Author : Tim Heistermann; Darko Beg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : A frame structure exposed to fire undergoes two types of changes due to the resulting temperature fields. The first is the thermal expansion of the structural members and the second is the degradation of the material strength and stiffness as temperature rises. READ MORE
