  1. 1. From CAD to FEA : A design automation perspective

    Författare :Roland Stolt; Högskolan i Jönköping; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Idealisation; CAD; Finite element analysis; mid-surfaces; KBES; Feature based modelling; knowledge based systems; TECHNOLOGY; TEKNIKVETENSKAP; Construction engineering; Konstruktionsteknik;

    Sammanfattning : CAD-models of parts produced by injection moulding or die-casting are often complex making the task of automated geometrical idealisation for finite element analysis difficult. Conventional tools for geometric idealisation are not ideal for the task, as will be shown in the thesis. LÄS MER

  2. 2. CAD adoption in the Swedish architectural industry : IT and the professional service sector

    Författare :Gert-Olof Boström; Umeå universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; professional service; information technology; service quality; competitive advantage; bottomlines; management visions; industry structure; dynamic service quality; CAD; architectural firms; innovation; Arkitektkontor; Informationsteknik; Datorstödd konstruktion; Sverige;

    Sammanfattning : The adoption of information technology (IT) is an intensive and ongoing process in society. All types of firms, but especially service firms, tend to adopt IT. Professional services, a sub-section of the service sector, are heavy users of IT. These firms are special because their business builds on the knowledge of the people in the firm. LÄS MER

  4. 4. CAD-Model Parsing for Automated Design and Design Evaluation

    Författare :Roland Stolt; Staffan Sunnersjö; Ola Isaksson; Högskolan i Jönköping; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design automation; CAD; KBE; Feature based modelling; Feature recognition; Product development.; Industrial engineering and economy; Industriell teknik och ekonomi; Product development; Design Automation;

    Sammanfattning : Product development has both innovative and analytic sides. Starting from the requirements, a design suggestion is generated. In order to assess how well the envisioned design fulfils the requirements, it is sometimes necessary to build a computer model of it for the analysis. LÄS MER

  5. 5. Adaptive structural design - Integration of computational tools for CAD, adaptive FEM and optimization

    Författare :Per Kettil; Chalmers University of Technology; []
    Nyckelord :Adaptive; structural mechanics; optimization; integration; FEM; CAD; design;

    Sammanfattning : BackgroundConstruction is one of the largest industries with major impact on economy, environment and society. Improved structural design is important since the decisions made during the design process strongly influence all later stages, i.e. LÄS MER
