1. 1. The Mirroring Immersed Boundary Method - Modeling Fluids with Moving and Interacting Bodies

   Detta är en avhandling från Chalmers University of Technology

   Författare :Andreas Mark; Chalmers tekniska högskola.; Chalmers University of Technology.; [2008]
   Nyckelord :MATEMATIK; MATHEMATICS; NATURVETENSKAP; NATURAL SCIENCES; SKOGS- och JORDBRUKSVETENSKAP samt LANDSKAPSPLANERING; FORESTRY; AGRICULTURAL SCIENCES and LANDSCAPE PLANNING; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Mirroring immersed boundary method; DNS; Fluid-structure interaction; Fiber;

   Sammanfattning : 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. LÄS MER

3. 2. Mixed mode loaded adhesive layers : from measurement of material data to analysis of structural behaviour

   Detta är en avhandling från Chalmers tekniska högskola

   Författare :Jia Li Högberg; Högskolan i Skövde.; Högskolan i Skövde.; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2007]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Technology; Teknik; adhesive layer; mixed mode testing; cohesive law; J-integral;

   Sammanfattning : 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. LÄS MER

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

   Detta är en avhandling från Chalmers University of Technology

   Författare :Göran Johansson; Chalmers tekniska högskola.; Chalmers University of Technology.; Chalmers tekniska högskola.; Chalmers University of Technology.; [2006]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; Large strains; Kinematic hardening; Ratcheting; Anisotropy; Plasticity;

   Sammanfattning : 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. LÄS MER

   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Adhesive joining; Dynamic fracture; Cohesive zone; Interphase Element; Bi-material joining; Hybrid joints;

   Sammanfattning : Today, crash simulations replace crash testing in the product development phase in the automotive industry. High quality simulations enable shorter product development time and higher competitiveness. LÄS MER

7. 5. Optimization of the Flow Process in Engine Bays - 3D Fan Modeling Strategies

   Detta är en avhandling från Chalmers University of Technology

   Författare :Peter Gullberg; Chalmers tekniska högskola.; Chalmers University of Technology.; [2009]
   Nyckelord :TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; TEKNIKVETENSKAP; TECHNOLOGY; Aerodynamics; Underhood Thermal Management; Cooling; CFD; Fan;

   Sammanfattning : In todays automotive industry there is an apparent need and demand for low fuel consuming vehicles. This is a fact every automotive OEM is aware of and the heavy duty truck industry is no exception. With a cooling fan in today’s trucks that typically consumes of the order of magnitude 50bHp fully engaged - reducing this loss is very important. LÄS MER
