  1. 6. FE modeling of glulam beams with mechanical slotted-in steel plate connections.

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Musaab Mahjoub; [2021]
    Keywords : Timber joints; Slotted-in steel plate connections; Python scripting; FEM; Abaqus.;

    Abstract : The mechanical behavior of timber beams with a slotted-in steel plate connection is studied by creating a numerical model that is able to simulate the global bending behavior, the global load carrying capacity and the nonlinear plastic fastener force distribution in the connection. Experimental results from Material Testing Institute (MPA), University of Stuttgart were used to verify the simulation results from this study. READ MORE

  3. 7. The Eemian Baltic Sea hydrography and paleoenvironment based on foraminiferal geochemistry

    University essay from Lunds universitet/Geologiska institutionen

    Author : Julia Chonewicz; [2020]
    Keywords : trace elements; benthic foraminifera; last interglacial; temperature reconstruction; geochemistry; Earth and Environmental Sciences;

    Abstract : I den här masteruppsatsen undersöktes geokemin i kalkskalen av bottenlevande foraminiferer från Anholt (Kattegat), Ristinge (Bälthavet) och Obrzynowo (Egentliga Östersjön), för att rekonstruera de hydrografiska förhållanden i Östersjön och paleomiljön under den senaste interglacialen (130 - 115 ka BP). De variabler som analyserades innefattade Mg/Ca, Ba/Ca och Mn/Ca samt stabila syre- och kolisotoper (δ18O och δ13C) i kombination med data från tidigare studier och modern hydrografi. READ MORE

  4. 8. Behaviour of cross laminated timber elements with openings at out-of-plane loading conditions

    University essay from Lunds universitet/Byggnadsmekanik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Christopher Hast; Daniel Fatemi; [2020]
    Keywords : CLT; Cross laminated timber; Grillage model; Gamma method; Bernoulli-Euler beam theory; Timoshenko beam theory; Finite element method; FEM; Composite; Abaqus; Technology and Engineering; Science General;

    Abstract : The use of cross laminated timber (CLT) is expanding, its use is relatively new and universal design standards are lacking. One situation for which no universal design standard exists is that of a CLT plate element with an opening. A grillage method has been proposed as a convenient method to design such plate elements.

  5. 9. The Weave - An Investigation into the Intersection of Craft and 3D-printing

    University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Albin Karlsson; Johanna Jonsson; [2019]
    Keywords : Arts and Architecture;

    Abstract : This project is a proposal for structural construction through fabrication and assembly of 3D-printed ceramic bricks developed side by side with a metaphysical investigation into the potential to express the living nature of matter through its material and formal attributes. Through an explorative process in the intersection of craft and digital fabrication, we have developed a system for LDM extrusion of composite bricks consisting of an outer ceramic shell and a low-density cementitious core, an integrated design flow based on procedural generation of fractal patterns and topological weaving, and an assembly logic capable of complex architectural expressions.

  6. 10. A Fabry–Pérot Cavity for Rare-Earth-Ion-Doped Nanocrystals

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Author : Andre Nüsslein; [2019]
    Keywords : Quantum Computer; Rear Earth Ions; Cavity; Laser; Cavity Quantum Electrodynamics; QED; Solidworks; Physics and Astronomy;

    Abstract : This thesis work contributes to the effort of detecting single rare earth ions doped into crystals, an operation crucial for the development of rare earth quantum computer hardware. Doping crystals with rare earth elements, their trivalent ions substitute some of the crystal’s original bonds. READ MORE
