  1. 21. Towards Automation of Non-Destructive Testing of Welds

    Författare :Patrik Broberg; Mikael Sjödahl; Anna Runnemalm; Torbjörn Löfqvist; Högskolan Väst; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Welding; non-destructive testing; NDT; Industriell arbetsvetenskap; Industrial engineering; Experimental Mechanics;

    Sammanfattning : All welding processes can give rise to defects that will weaken the joint and can lead to failure of the welded structure. Because of this, non-destructive testing (NDT) of welds have become increasingly important to ensure the structural integrity when the material becomes thinner and stronger and welds become smaller; all to reduce weight in order to save material and reduce emissions due to lighter constructions.

  3. 22. Material characterisation for crash modelling of composites

    Författare :Thomas Bru; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mechanical testing; finite element analysis FEA ; non-crimp fabric NCF ; damage mechanics; carbon fibre composite; crushing;

    Sammanfattning : The transport industry must find solutions to reduce its impact on climate change. A promising way to reduce the weight of vehicles and therefore to reduce the CO2 emissions is to introduce components made of lightweight composite materials, in particular carbon fibre reinforced plastics (CFRPs).

  4. 23. Material characterisation for simulation of press hardening

    Författare :Paul Åkerström; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The growing effort to reduce vehicle weight and improve passive safety in the automotive industry has drastically increased the demand for ultra high strength steel components. There exist several production methods for such components, where the press hardening technique (hot stamping) is one of the most successful in producing complex components from boron steel. LÄS MER

  5. 24. Simulation of Microstructure-based Mechanical Behaviour of Cast Components

    Författare :Jakob Olofsson; Ingvar L. Svensson; Salem Seifeddine; Franco Bonollo; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Component behaviour; structural analysis; mechanical behaviour; casting process simulation; Finite Element Method FEM simulation;

    Sammanfattning : In the process of developing cast iron and cast aluminium components, a high level of co-operation between product development and production is of great importance. From an engineering standpoint, this co-operation is limited early in the product development phase by e.g. LÄS MER

  7. 25. On the mechanics of actin and intermediate filament networks and their contribution to cellular mechanics

    Författare :Björn Fallqvist; Kroon Martin; Peter McHugh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; actin; cell; mechanical; constitutive; intermediate; continuum; constitutive; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The mechanical behaviour of cells is essential in ensuring continued physiological function, and deficiencies therein can result in a variety of diseases. Also, altered mechanical response of cells can in certain cases be an indicator of a diseased state, and even actively promoting progression of pathology. LÄS MER
