  1. 1. Additives in a steam engine to decrease friction : Friction testing of solid lubricants in powder form

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Viktor Lange; [2023]
    Keywords : Tribology; friction; wear; steam; steam engine; ranotor; invencon; invencon AB; steel; contact mechanics; hexagonal boron nitride; molybdenum disulfide; tungsten disulfide; lubricants; solid lubricants; Tribologi; friktion; nötning; ånga; ångmotor; stål; kontaktmekanik; smörjning; smörjmedel; fasta smörjmedel;

    Abstract : This thesis aims to investigate the coefficient of friction between steel on steel contacts with the addition of solid lubricants such as h-BN, WS2, MoS2 in powder form, in dry conditions and wet conditions. More specifically, the purpose is to enhance the sliding between the piston rings and cylinder block in a modern high temperature steam engine developed by RANOTOR. READ MORE

  2. 2. Plastic deformation of hot riveted joints acting in shear

    University essay from KTH/Bro- och stålbyggnad

    Author : Victor Gard; [2023]
    Keywords : ;

    Abstract : A popular way to maintain old rivet connections is to reuse the old connection and replace the old rivets with high grade steel bolts. In doing so the behavior of the joint can change due to the new geometry, where a gap between the new bolt and the rivet hole emerges. READ MORE

  3. 3. ”The shrieking of nothing is killing me” : Representations of society of the spectacle and hyperreality in David Bowie’s lyrics

    University essay from Mittuniversitetet/Institutionen för humaniora och samhällsvetenskap

    Author : Mariann Gabrielsson; [2023]
    Keywords : ;

    Abstract : This text explores how the lyrics of David Bowie can be applied as supporting the critique against hyperreality and society of the spectacle, as articulated by Guy Debord and Jean Baudrillard. This is done by focusing on three questions: 1) what elements in Bowie’s lyrics support Debord and Baudrillard, 2) how can these elements function to portray Bowie as primarily a sociologist and secondly an artist, and 3) what are the benefits of using fiction (in this case lyrics) as empirical material? From a theoretical framework building on Debord’s society of the spectacle and Baudrillard’s focus on hyperreality, I will apply a two-folded methodology of sociology through literature and socio-poetics.

  4. 4. Embedment Behavior of Steel Dowel in Timber Loaded Perpendicular to the Grain : Influence of Assembly History in Combination with Moisture Change and Cyclic Loading

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Mojtaba Khalili; [2023]
    Keywords : Embedment strength; elastic and plastic embedment stiffness; moisture content; swelling and shrinkage; steel dowel; assembly history; cyclic loading;

    Abstract : The embedment behavior of dowels in timber structures, as an essential parameter in the design of connections, is the subject of this thesis. There are numerous advantages using timber structures, including sustainability, energy efficiency, and aesthetic appeal. READ MORE

  5. 5. Validation of An Iteration Free Material Model for Paperboard (NEO)

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

    Author : Samuel Thomas Staines; [2022]
    Keywords : Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Abstract : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. READ MORE
