  2. 1. Shear Behaviour of Adhesive Layers

    Author : Karin Leffler; Högskolan i Skövde; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adhersive layer; shear; ENF-specimen; stress-deformation relation; experimental method; J-integral; inverse method; Engineering mechanics; Teknisk mekanik; Teknik; Technology;

    Abstract : An experimental method to determine the complete stress versus deformation relation for a thin adhesive layer loaded in shear is presented. The work is based on a classical specimen geometry, i.e. the end-notch flexure specimen (ENF-specimen) and the experiments are evaluated based on an inverse method. READ MORE

  4. 2. Behaviour of fracture process zones in concrete influenced by simultaneously applied normal and shear displacements

    Author : Manouchehr Hassanzadeh; Avdelningen för Byggnadsmaterial; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; softening; mixed mode; fictitious crack model; concrete; deformationer; betong; brottmekanik; hållfasthet; brotthållfasthet; spänningar; skjuvspänningar; sprickor; beräkningsmodeller; brottenergi; teori; laboratorieförsök; interlock; crack path; diagonal crack; microcracking; instability; fracture energy; fracture mechanics; shear; tension; process zone;

    Abstract : The thesis deals with the determination of the post peak behaviour of concrete in pure tension, and combined tension (compression) and shear. A test arrangement has been developed in order to determine the post peak behaviour of concrete expressed as stress - displacement curves. READ MORE

  5. 3. 2D and 3D Reflection Seismic Studies over Scandinavian Deformation Zones

    Author : Emil Lundberg; Christopher Juhlin; Alireza Malehmir; Lars Nielsen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Azimuthal binning; Crooked-line geometry; Cross-dip; Fault zone; Hard rock seismics; MTFC; Quick clay; Shear zone; UDZ; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Abstract : The study of deformation zones is of great geological interest since these zones can separate rocks with different characteristics. The geometry of these structures with depth is important for interpreting the geological history of an area. READ MORE

  6. 4. Assessment of rock mass quality and its effects on charge ability using drill monitoring technique

    Author : Rajib Ghosh; Håkan Schunnesson; Nuray Demirel; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underground mining; Sublevel caving; Rock mass quality; Borehole filming; Borehole quality; Borehole stability; Borehole instability; Drill monitoring technique; Measurement While Drilling MWD ; Hydraulic in-the-hole ITH drilling; Drill system behaviour; Principal Component Analysis PCA ; Geo-mechanical model; Chargeability; Fracture zone; Shear zone; Cave-in; Cavity; Rock blasting; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : For an efficient mining operation, it is essential to have as much information as possible aboutthe ore to be excavated and the rock masses surrounding the ore. Geological information andthe content and distribution of extractable minerals, are central concerns for long term mineplanning. READ MORE

  7. 5. Fibre flow mechanisms

    Author : Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Abstract : The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. READ MORE
