  2. 16. Analysis of Seismic Data Acquired at the Forsmark Site for Storage of Spent Nuclear Fuel, Central Sweden

    Author : Fatemeh Sharifi Brojerdi; Christopher Juhlin; Alireza Malehmir; Bjarne Almqvist; Ramon Carbonell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Forsmark site; anisotropy; deformation zone; reflection seismic; shear-wave splitting; fractures and traveltime tomography;

    Abstract : The Forsmark area, the main study area in this thesis, is located about 140 km north of Stockholm, central Sweden. It belongs to the Paleoproterozoic Svecokarelian orogen and contains several major ductile and brittle deformation zones including the Forsmark, Eckarfjärden and Singö zones. READ MORE

  4. 17. Modeling of Inelastic Response of Metals with Emphasis on Cyclic Viscoplasticity

    Author : Magnus Ekh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; large strains; integration; anisotropy; plasticity; creep; viscoplasticity; kinematic hardening; metals; damage; calibration;

    Abstract : This thesis is concerned with the continuum modeling of the macroscopic behavior of engineering metals, in particular as part of life prediction strategies. Focus is primarily placed on the formulation and numerics of models for cyclic rate-dependent response. READ MORE

  5. 18. Experimental study and simulation of sintering of 316L components produced by binder jetting

    Author : Alberto Cabo Rios; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; binder jetting; 316L stainless steel; additive manufacturing; dilatometry; sintering modelling; Sintering; anisotropy;

    Abstract : Binder Jetting (BJT) is a multi-step Additive Manufacturing (AM) technique that is used for producing components with highly complex geometries and competitive final properties with high productivity when compared to other AM technologies. The first step provides the basic part geometric shape (BJT printing), and the next step (debinding and sintering) consolidates the part to reach final geometry and intended basic material properties.

  6. 19. Molecular electronic,  vibrational and rotational motion in optical and x-ray fields

    Author : Sergey Gavrilyuk; Faris Gelmukhanov; Stephane Carniato; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray; nonlinear optics; photobleaching; recoil; anisotropy; Auger; Chemical physics; Kemisk fysik;

    Abstract : The subject of this theoretical  study is the role ofelectronic structure as well as of rotational and vibrational motionson interactions between molecules and electromagnetic radiation,ranging from optical to x-ray. The thesis concerns both linear and nonlinear regimes of the light-matter interaction. READ MORE

  7. 20. Continuum modeling of the mechanical properties of paperboard

    Author : Eric Borgqvist; Hållfasthetslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; director vectors; polyconvexity; plastic spin; creasing; anisotropy; fiberous materials; Continuum Modeling; Paperboard;

    Abstract : Continuum based elasto-plastic models for paperboard have been established in the work herein. The thesis begins with an introductory section that describes some of the background of the problem and gives some more motivation for the modeling choices made in the appended papers. READ MORE
