  1. 1. Environmental Perspectives on Urban Material Stocks used in Construction : Granular Materials

    Författare :Simon Magnusson; Sven Knutsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : The peoples demand of functions and services in cities is the driver for energy and material flows. Most people in the world are now living in urban areas. In order to achieve a sustainable development of cities, both resource use and environmental impact have to be reduced. LÄS MER

  3. 2. Decarbonising the Stainless Steelmaking through Alloy Solutions

    Författare :Wenjing Wei; Pär Jönsson; Peter Samuelsson; Birat Jean Pierre; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; optimization; raw material; process; quality; decarbonisation; rostfritt stål; optimering; material; process; kvalitet; avkarbonisering; Materials Science and Engineering; Teknisk materialvetenskap;

    Sammanfattning : To reach the goal of the Paris Agreement, the reduction of greenhouse gas emissions (GHG)is becoming one of the most pressing issues in the world today. Unlike most other sectors, thestainless steel industry has a significantly higher burden from upstream emissions comparedto operational emissions. LÄS MER

  4. 3. The double axe in Minoan Crete : a functional analysis of production and use

    Författare :Maria Lowe Fri; Charlotte Scheffer; Lena Sjögren; Doniert Evely; Stockholms universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Bronze Age Crete; Minoan period; double axe; casting; casting defects; finishing treatment; experimental archaeology; use-wear; use; user; Archaeology; classical; Arkeologi; klassisk; antikens kultur och samhällsliv; Classical Archaeology and Ancient History;

    Sammanfattning : This study examines the production and use of Minoan double axes with the aim of finding out what working activities they were used for. The double axe has earlier been associated with a woodworker, a carpenter, a stonemason and a butcher. LÄS MER

  5. 4. Shear Fracture and Delamination in Packaging Materials : A study of Experimental Methods and Simulation Techniques

    Författare :Md. Shafiqul Islam; Sharon Kao-Walter; Christian Johansson; Johan Tryding; Blekinge Institute of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Package opening; Shear test specimen; Stress intensity factor; Finite Element simulation; Scanning electron microscopy; Polymers; Interlaminar shear delamination;

    Sammanfattning : Packages are the means of preservation, distribution and convenience of use for food, medicine and other consumer products. Package opening is becoming complicated in many cases because of cutting cost in design and production of opening techniques. LÄS MER

  7. 5. On failure modelling in finite element analysis : material imperfections and element erosion

    Författare :Mattias Unosson; Larsgunnar Nilsson; Kjell Simonsson; Lars Olovsson; Anders Eriksson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; element erosion; material failure; material imperfections; crack-tip; Solid mechanics; Fastkroppsmekanik;

    Sammanfattning : This dissertation concerns failure modelling with material imperfections and element erosion in finite element analyses. The aim has been to improve the element erosion technique, which is simple to use and implement and also computationally inexpensive. LÄS MER
