  1. 1. Dissimilar joining of aluminium to ultra-high strength steels by friction stir welding

    Författare :Wallop Ratanathavorn; Arne Melander; Gunnar Bolmsjö; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium alloy; high strength steel; intermetallic; friction stir welding; dissimilar joining; SRA - Produktion; SRA - Production;

    Sammanfattning : Multi-material structures are increasingly used in vehicle bodies to reduce weight of cars. The use of these lightweight structures is driven by requirements to improve fuel economy and reduce CO2 emissions. The automotive industry has replaced conventional steel components by lighter metals such as aluminium alloy. LÄS MER

  3. 2. Development and evaluation of hybrid joining for metals to polymers using friction stir welding

    Författare :Wallop Ratanathavorn; Arne Melander; Stefan Hallström; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloy; thermoplastic; friction stir welding; dissimilar joining; Production Engineering; Industriell produktion;

    Sammanfattning : Combinations of different materials are increasingly used in the modern engineering structures. The driving forces of this trend are rising fuel costs, global warming, customer demands and strict emission standards. LÄS MER

  4. 3. Impact Simulation of Adhesively Joined Structures

    Författare :Thomas Carlberger; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhesive joining; Dynamic fracture; Cohesive zone; Interphase Element; Bi-material joining; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Sammanfattning : The development of competitive and crashworthy automotive car bodies has reached so far that the manufacturers no longer rely on mono-material steel structures. Improved strength/weight performance may be achieved by using optimal material in each part of the car structure, leading to bi-material joints and ruling out spot welding; the common joining method during the past half century of automotive history.

  5. 4. Application of cohesive modeling in joining technology : Thick adhesive layers and rivet joints

    Författare :Saeed Salimi; Högskolan i Skövde; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknik; Technology;

    Sammanfattning : This thesis summarizes the development of cohesive modeling of joints. It presents some new developments regarding the effects of non-zero thickness of adhesive layers and a novel approach of using the concept of cohesive modeling to characterize the failure behavior of rivet joints.
