  1. 1. In-situ testing of floating thermal piles in soft sensitive clay

    Author : Anders Bergström; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maintained; Cyclic Thermal loading; Energy piles; Field Test; Thermal Piles;

    Abstract : Thermal piles are structural piles with additional function of working as geothermal heat exchangers towards the soil volume. Heating and cooling process of soft soils is known to affect the stress state and soil structure, with potential consolidation settlements and creep as undesired consequences. READ MORE

  3. 3. Oviposition strategies in butterflies and consequences for conservation

    Author : Anders Bergström; Sören Nylin; Jeremy A. Thomas; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Oviposition strategies are an important component of life history evolution in insects. Oviposition is a complex behaviour, where females must locate suitable habitat patches, locate oviposition sites, evaluate the quality, and finally decide how many eggs to lay. READ MORE

  4. 4. On Tool Failure in Die Casting

    Author : Anders Persson; Sture Hogmark; Jens Bergström; Torsten Eriksson; Uppsala universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Die casting is a very cost-efficient method of forming thin-walled and complex near net-shaped products with close geometric tolerances and good surface finish. A permanent die tool is used to make large quantities of identical products. The performance and tool life are limited by several mechanisms, e.g. READ MORE

  5. 5. Wear in sheet metal forming

    Author : Anders Gåård; Pavel Krakhmalev; Jens Bergström; Åsa Kassman; Karlstads universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Friction; Sheet metal forming; Galling; Materials science; Teknisk materialvetenskap; Materialteknik; Materials Engineering;

    Abstract : The general trend in the car body manufacturing industry is towards low-series production and reduction of press lubricants and car weight. The limited use of press lubricants, in combination with the introduction of high and ultra-high strength sheet materials, continuously increases the demands of the forming tools. READ MORE
