  1. 1. Experiments and modelling of fracture initiation at impact

    Author : Ola Wall; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration and acoustic engineering; vacuum technology; hydraulics; Viscoplasticity; Mechanical engineering; Ductile; Brittle; Dynamic; Fracture; Maskinteknik; hydraulik; vakuumteknik; vibrationer; akustik; Material technology; Materiallära; materialteknik;

    Abstract : The thesis addresses different questions, each necessary in the understanding of dynamic fracture initiation and crack propagation in steel. Emphasis lays on dynamic crack propagation experiments performed in the ductile to brittle transition region and possible conclusions, that can be drawn from them. READ MORE

  2. 2. Techniques for Distributed Access and Visualisation in Computational Mechanics

    Author : Jonas Lindemann; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; finite element method; visualisation; computational mehcanics; distributed systems;

    Abstract : This work concern ideas and methods on how the context of computational mechanics can be improved for more efficient utilisation and extended into areas previously not familiar with or capable of using such tools. Three main areas were studied: Providing efficient and transparent access to finite element applications, development of methods for the visualisation of complex phenomena and improving the usability of the finite element method, partly in an educational context.

  3. 3. Property-Oriented Information Systems for Design Prototypes for the BAS•CAAD system

    Author : Sverker Fridqvist; Byggproduktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anläggningsteknik; Construction technology; product modelling; construction; information technology; design; Data- och systemvetenskap; computer technology; Systems engineering;

    Abstract : Property-oriented systems are a new kind of information systems that are based on concepts of properties instead of concepts of things or classes of things. By focusing on properties, the property-oriented systems become more flexible and more suited to the dynamic early stages of design than the traditional class-oriented systems can be. READ MORE

  4. 4. Vibration transmission in lightweight buildings : Numerical prediction models

    Author : Ola Flodén; Byggnadsmekanik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vibration transmission; structure-borne sound; wood buildings; numerical modelling; finite element method; structure-acoustic coupling; model validation; model calibration; dynamic substructuring; model order reduction;

    Abstract : Ljud från grannar är ett återkommande problem för boende i flerfamiljshus. Problemen är generellt mer omfattande för de som bor i flervåningshus byggda i trä, en byggnadstyp som blir allt vanligare i Sverige. Många av de boende i trähus upplever även att störande vibrationer är vanligt förekommande i trähus. READ MORE

  5. 5. Knowledge processes and capabilities in project-based organizations

    Author : Sofia Pemsel; Byggproduktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; PBO; project; knowledge process; capabilities; end-user; real estate sector; PMO; knowledge governance; bridging boundaries; critical realism;

    Abstract : The beauty of projects lies in their ability to integrate different knowledge bases and expertise in novel ways. Projects, though, are temporary in nature and this has consequences for the organization that uses them as a business strategy to improve its efficiency. READ MORE
