  1. 6. Patch loading of stainless steel girders : experiments and finite element analyses

    Författare :Emma Unosson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis deals with the behaviour of stainless steel girders subjected to patch loading. The current loading situation arises for example at beam- column connections or at crane girders where the load is travelling along a girder. At bridge launching it is also important to consider patch loading. LÄS MER

  3. 7. Behaviour and resistance of composite slabs : experiments and finite element analysis

    Författare :Milan Veljkovic; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : Composite slab flooring systems are used in steel framed buildings as well as in conjunction with concrete, prestressed concrete and timber structures. Composite slabs consist of a thin-walled profiled steel sheet, reinforcement and in-situ cast concrete. LÄS MER

  4. 8. Alternatives for Finite Element Analysis of Blade Forging

    Författare :Behzad Soltani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residual stresses; blade forging; flow approach; metal forming; quasistatic implicit; dynamic explicit; forging; solid approach; finite element method; closed die forging;

    Sammanfattning : This thesis is a theoretical and numerical study of the weaknesses and capabilities of alternative finite element procedures for simulation of the blade forging problem and also an analysis of the practical aspects of that process. An overview is presented of the finite element method for non-linear problems with elastoplastic constitutive relations, focusing on quasistatic implicit and dynamic explicit approaches. LÄS MER

  5. 9. Finite Element Simulations of Biphasic Articular Cartilages With Localized Metal Implants

    Författare :Krishnagoud Manda; Anders Eriksson; Ingrid Svensson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element analysis; articular cartilage defects; knee joint; metal implant; poroelastic; biphasic; Other engineering mechanics; Övrig teknisk mekanik;

    Sammanfattning : Articular cartilage is a specialized connective soft tissue that resides onthe ends of long-bones, transfers the load smoothly between the bones in diarthrodialjoints by providing almost frictionless, wear resistant sliding surfacesduring joint articulation. Focal chondral or osteochondral defects in articularcartilage are common and show limited capacity for biological repair. LÄS MER

  7. 10. Seat integrated safety belts : a parametric study using finite element simulations

    Författare :Anders Gavelin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : In recent years an increasing interest has evolved concerning seat integrated safety belts in cars, regarding both 3- and 4-point belts in various configurations. One safety advantage of seat integrated safety belts appears in the case of so-called small overlap crashes. LÄS MER
