  2. 1. Modeling of foams for impact simulations

    Author : Mats L Landervik; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Theory of Porous Media; Shell theory.; Constitutive modeling; Multiscale Analysis; Foams; Computational Homogenization;

    Abstract : Stimulated by the strong drive in the automotive industry to reduce energy consumption,and, linked to that, the need to reduce weight, this thesis concerns modeling of foams forimpact simulations. To start with, a continuum hyperelasto-viscoplastic model is developedwithin the framework of Theory of Porous Media. READ MORE

  4. 2. Resistance of Friction Connections with Open Slotted Holes in Towers for Wind Turbines

    Author : Christine Heistermann; Peter Schaumann; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : The most common solutions for in-situ connections of steel tubular towersegments of onshore wind turbines are ring flange connections. These havecertain drawbacks, such as e.g. costly production, long delivery time and ratherlow fatigue endurance. READ MORE

  5. 3. JupiterNCSM: A Pantheon of Nuclear Physics —an implementation of three-nucleon forces in the no-core shell model—

    Author : Tor Djärv; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : It is well established that three-nucleon forces (3NFs) are necessary for achieving realistic and accurate descriptions of atomic nuclei. In particular, such forces arisenaturally when using chiral effective field theories (χEFT). READ MORE

  6. 4. Evolution and ecology of Baltic late Ordovician univalved molluscs

    Author : Jan Ove Rõysi Ebbestad; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Earth sciences; Geovetenskap; Earth sciences; Geovetenskap; Historical Geology and Paleontology; historisk geologi och paleontologi;

    Abstract : Univalved molluscs (Gastropoda and Tergomya) are common fossils in the Palaeozoic succession across Baltoscandia, but most of the more embracive descriptive works on this group appeared before or near the turn of the 19th century. The study presented here aims at revision and description of some Baltoscandian late Ordovician/early Silurian univalved molluscs with emphasis on their shell morphology. READ MORE

  7. 5. Phenotypic Processes Triggered by Biological Invasions

    Author : Philipp E Hirsch; Richard Svanbäck; Skúli Skúlason; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resource polymorphism; phenotypic plasticity; phenotypic divergence; anti-predator responses; Perca fluviatilis; Rutilus rutilus; Dreissena polymorpha; Biology with specialization in Limnology; Biologi med inriktning mot limnologi;

    Abstract : Individuals within a single population can vary widely in their phenotype e.g. in their body shape. These differences are an important source of biodiversity and they can precede evolutionary divergence within a population. READ MORE
