  2. 1. Remote Acoustic Characterization of Thin Sheets

    Author : Etienne Mfoumou; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Remote acoustic excitation; material characterization; acoustic NDT; vibration-based technique; sheet material evaluation; fracture toughness.;

    Abstract : There is a need to monitor the existence and effects of damage in structural materials. Aircraft components provide a much publicized example, but the need exists in a variety of other structures, such as layered materials used in food packaging industries. READ MORE

  4. 2. The mutual interaction between the time-mean atmospheric circulation and continental-scale ice sheets

    Author : Johan Liakka; Johan Nilsson; Johan Kleman; Gerard Roe; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Atmospheric stationary waves; Paleo ice sheets; Ice-sheet ablation; Atmosphere-ice sheet modelling; Climatology; Klimatologi; Meteorology; Meteorologi; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Abstract : Geomorphological evidence of glaciations exist for the Last Glacial Maximum (about 20 kyr ago). At this time, both North America and Eurasia were covered by extensive ice sheets which are both absent today. READ MORE

  5. 3. Ductile Failure in High Strength Steel Sheets

    Author : Oscar Björklund; Larsgunnar Nilsson; Odd-Geir Lademo; Linköpings universitet; []
    Keywords : ;

    Abstract : Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usage. READ MORE

  6. 4. Modelling of Failure in High Strength Steel Sheets

    Author : Oscar Björklund; Larsgunnar Nilsson; Odd Geir Lademo; Linköpings universitet; []
    Keywords : ;

    Abstract : In this theses the high strength steel Docol 600DP and the ultra high strength steel Docol 1200M are studied. Constitutive laws and failure models are calibrated and veried by the use of experiments and numerical simulations. READ MORE

  7. 5. On Material Modelling of High Strength Steel Sheets

    Author : Rikard Larsson; Larsgunnar Nilsson; Odd-Sture Hopperstad; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material modelling;

    Abstract : The work done in this thesis aims at developing and improving material models for use in industrial applications.The mechanical behaviour of three advanced high strength steel grades, Docol 600DP, Docol 1200M and HyTens 1000, has been experimentally investigated under various types of deformation, and material models of their behaviour have been developed.
