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

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

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lars Olof Jernkvist; Malmö University.; Malmö University.; [2000]
    Keywords : Hållfasthetslära; Solid Mechanics; TECHNOLOGY; TEKNIKVETENSKAP; Technology;

    Abstract : 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. READ MORE

  3. 3. Algorithms for aggregate information extraction from sequences

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Fredrik Bengtsson; Luleå tekniska universitet.; Malmö University.; Malmö University.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dependable Communication and Computation Systems; Kommunikations- och beräkningssystem; TECHNOLOGY; TEKNIKVETENSKAP; Technology;

    Abstract : In this thesis, we propose efficient algorithms for aggregate information extraction from sequences and multidimensional arrays. The algorithms proposed are applicable in several important areas, including large databases and DNA sequence segmentation. READ MORE

  4. 4. Fracture mechanical modelling of embossed paper

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Rickard Hägglund; Malmö University.; Malmö University.; [2001]
    Keywords : Hållfasthetslära; Solid Mechanics; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Technology;

    Abstract : This thesis consists of two scientific papers on strength and fracture of embossed tissue paper. In Paper A an experimental study of embossed tissue paper is presented. The mechanical properties of most soft tissue paper are to a large extent governed by the creping and subsequent embossing process. READ MORE

  5. 5. Vibro-impact dynamics of fretting wear

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Jakob Knudsen; Malmö University.; Malmö University.; [2001]
    Keywords : Hållfasthetslära; Solid Mechanics; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Technology;

    Abstract : The dynamics and wear of non-linear impact oscillators, comprising a single-degree of freedom system as well as continuous beam systems are analysed. The considered beams are of cantilever type with the lateral motion of the free end constrained by elastic supports. They are modelled as Bernoulli beams with Rayleigh damping. READ MORE
