  3. 2. Development and application of corotational finite elements for the analysis of steel structures in fire

    Författare :Luca Possidente; Jean-Marc Battini; Nicola Tondini; Paulo Vila Real; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermomechanical finite element; Shell element; 3D beam element; Steel structures; Buckling; Fire Safety Engineering; Structural Engineering and Bridges; Bro- och stålbyggnad;

    Sammanfattning : The ignition and the propagation of a fire inside a building may lead to global or local structural collapse, especially in steel framed structures. Indeed, steel structures are particularly vulnerable to thermal attack because of a high value of steel conductivity and of the small thickness that characterise the cross-sections. LÄS MER

  4. 3. Modelling of Delamination Growth in Composite Structures

    Författare :Niklas E. Jansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large deformation; interface; composite materials; 3D-shell; cohesive zone; regularization; shell element; delamination;

    Sammanfattning : Delaminations constitute an important damage and failure mode in polymeric composite laminates. In order to explicitly incorporate and model the delamination progression within a finite element analysis, the meso-modelling concept is applied in the present work. The laminate is thereby represented by separate layers connected with interfaces. LÄS MER
