  2. 1. Systematic planning and execution of finite element model updating

    Author : Joakim Wallin; Costin Pacoste; Raid Karoumi; Mario Plos; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; finite element model updating; bridge; objective function; updating parameter; mode pairing; dynamik; finita element modelluppdatering; bro; målfunktion; uppdateringsparameter; matchning av moder; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : In design of bridges and for estimation of dynamic properties and load carrying capacity Finite Element Method (FEM) is often used as a tool. The physical quantities used in the Finite Element (FE) model are often connected to varying degrees of uncertainty. READ MORE

  4. 2. Internal Cooling Design Using Multiphysics Topology Optimization

    Author : Jonas Lundgren; Carl-Johan Thore; Anders Klarbring; Jan-Erik Lundgren; Joe Alexandersen; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis investigates topology optimization (TO) as a tool for designing optimal internal cooling configurations in components subjected to external hot gas streams. The work is motivated by the challenge of simultaneously considering objectives from multiple physics domains, and the rapid development of additive manufacturing (AM) in the industry, which makes it possible to realize highly complex TO designs.
