  1. 1. On crack growth under compressive stresses

    Detta är en avhandling från Luleå : Univ

    Författare :Per Isaksson; Mittuniversitetet.; Mittuniversitetet.; Malmö University.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik; Ph.D. Thesis; Fracture mechanics; Hållfasthetslära; Solid Mechanics; TECHNOLOGY; TEKNIKVETENSKAP; Technology;

    Sammanfattning : This thesis concerns fractures subjected to compressive stresses. In the four papers appended fracture behavior in brittle as well as ductile materials is studied. LÄS MER

  2. 2. On the fracture behaviour of softwood a combined experimental and computational study of the interaction between fracture behaviour and material anatomy

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Lars Olof Jernkvist; Malmö University.; [2000]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics; TECHNOLOGY; TEKNIKVETENSKAP; Technology;

    Sammanfattning : The propensity for fracture, i.e. failure through separation of the material, is a factor that must be regarded in the design of wooden structures, but also in wood machining operations and drying. LÄS MER

  3. 3. Material Hygiene An EcoDesign mindset for recycling of products

    Detta är en avhandling från Stockholm : KTH

    Författare :Jan Johansson; KTH.; [2008]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In recent years the end-of-life phase has come into focus. European Union directives have been issued regulating certain product groups and producer responsibility. Vehicles and electronic products are the first to be identified and targeted. EU environmental legislation acts as a driver for increased reuse, recycling and recovery. LÄS MER

  4. 4. Cathodic arc deposition process

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Muhammad Bilal Syed; Linköpings universitet.; Linköpings universitet.; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis aims to expand the knowledge of fundamental mechanisms that govern the cathodic arc process. The first part of this thesis explores and explains the correlations between a rather unexplored process parameter (i.e. cathode microstructure) and the microstructure of the coatings. LÄS MER

  5. 5. Phase field modeling of flaw-induced hydride precipitation kinetics in metals

    Detta är en avhandling från Chalmers University of Technology

    Författare :Claudio F. Nigro; Malmö University.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY; TEKNIKVETENSKAP; Technology; hydride; phase field theory; linear elastic fracture mechanics; finite element method; phase transformation; hydrogen embrittlement; finite volume method;

    Sammanfattning : Hydrogen embrittlement can manifest itself as hydride formation in structures when in contact with hydrogen-rich environments, e.g. in space and nuclear power applications. To supplant experimentation, modeling of such phenomena is beneficial to make life prediction reduce cost and increase the understanding. LÄS MER
