  2. 1. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

    Author : Dan Engström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

    Abstract : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. READ MORE

  4. 2. Modeling of rigid foams

    Author : Joonas Köll; Dan Zenkert; Lorna Gibson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The morphology and elastic properties of foams are investigated using models accounting for the cellular structure. Different modeling approaches are evaluated and compared to the cellular structures of real foams. The aim is to find an approach that produces realistic models that can be adjusted to match morphology measures taken form real foams. READ MORE

  5. 3. Dynamic fail-safe behaviour of steel structures

    Author : Ulf Arne Girhammar; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träbyggnad; Timber Structures;

    Abstract : The fundamental behaviour and the capacity of steel structures subjected to loss of interior load-bearing elements are studied. The ultimate load-bearing and deformation capacity of certain beam-to-column connections and the dynamic fail-safe behaviour of some ordinary steel structures are investigated in detail. READ MORE

  6. 4. Laser sintered materials with Non-equilibrium structures

    Author : Bin Qian; Zhijian Shen; Germán F. de la Fuente; Stockholms universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Laser sintering; Materials; Non-equilibrium structures; microstructure; hierarchical structure; Inorganic Chemistry; oorganisk kemi;

    Abstract : This thesis is focused on achieving materials with non-equilibrium structures fabricated by high-energy laser sintering. The chosen precursor materials have rigid and inert structures like high-melting point ceramics or metals. READ MORE

  7. 5. Adaptive Bounding Volume Hierarchies for Efficient Collision Queries

    Author : Thomas Larsson; Björn Lisper; Tomas Akenine-Möller; Stefane Redon; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bounding volume hierarchies; Collision detection; Rigid bodies; Deformable models; Data structures; Simulation; Animation; Three-dimensional graphics and realism; Computer science; Datavetenskap; Datavetenskap;

    Abstract : The need for efficient interference detection frequently arises in computer graphics, robotics, virtual prototyping, surgery simulation, computer games, and visualization. To prevent bodies passing directly through each other, the simulation system must be able to track touching or intersecting geometric primitives. READ MORE
