    Abstract : In manufacturing of multi-material products, a joining method that is able to cost-effectively assemble components made of dissimilar and similar material, with irregular geometries, is optimal. As an alternative, adhesive bonding is in-creasingly adapted by the industry, which is also used in manufacturing of multi-phase materials. READ MORE

  2. 2. Implementation of a flexible fiber model in a general purpose CFD code

    University dissertation from Chalmers University of Technology

    Author : Jelena Andric; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fastkroppsmekanik; Solid mechanics; Strömningsmekanik; Fluid mechanics; flexible fiber; LPT; CFD; OpenFOAM;

    Abstract : This work is related to the process of making pulp mats for use in hygienic products. One part of that process is the transportation of flexible cellulose fibers suspended in flowing air. The fibers should be evenly distributed on the substrate, and it is thus of high importance to avoid the formation of fiber flocks during the transportation. READ MORE

    Abstract : The detailed fluid flow around arbitrary, moving, interacting and deforming bodies is both complex and poorly understood and the commercial simulation tools simulating such flows are computationally to demanding. Hence, a new fast and accurate method for simulating complex multi-body flows is required. READ MORE

  4. 4. Multiscale modeling of dynamic recrystallization

    University dissertation from Avd för Hållfasthetslära, Box 118, 221 00 Lund

    Author : Ylva Mellbin; Lunds universitet.; Lund University.; [2016-09-16]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic recrystallization; Crystal plasticity; Texture; Grain size strengthening; Vertex model; Nucleation; Particle pinning; Large deformations; Multiscale modeling; GPGPU;

    Abstract : During thermomechanical processing of metals, changes occur in the microstructure of the material which affect its macroscopic properties. By understanding these transformations in the microstructure, it becomes possible to design the processes in a way which yields the desired properties in the finished product. READ MORE

  5. 5. On the modeling of large ratcheting strains and anisotropy in pearlitic steel

    University dissertation from Chalmers University of Technology

    Author : Göran Johansson; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fastkroppsmekanik; Solid mechanics; Large strains; Kinematic hardening; Ratcheting; Anisotropy; Plasticity;

    Abstract : Thermodynamically consistent constitutive material models for describing the large strain response of polycrystalline metals are proposed. Emphasis is put on the multiaxial ratcheting under cyclic loading and the evolution of anisotropy in pearlitic steel. READ MORE
