  1. 1. Drop-weight impact tests on reinforced concrete beams

    University essay from KTH/Betongbyggnad

    Author : John Abdalnour; Milad Saliba; [2023]
    Keywords : ;

    Abstract : This master's thesis aimed to investigate the behaviour of reinforced concrete beams under dynamic loading conditions, specifically focusing on understanding shear failure. The study was conducted with KTH Royal Institute of Technology, the Swedish Fortifications Agency, and Tyréns. READ MORE

  3. 2. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Chun Hei Ho; [2023]
    Keywords : Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Abstract : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. READ MORE

  4. 3. Finite Element Macro-modeling of a Historical Masonry Building : Influence of Isotropic vs Anisotropic Plastic Material Model Assumption in Static Analysis

    University essay from KTH/Bro- och stålbyggnad

    Author : Madeleine Olsson; Maja Gustavsson; [2023]
    Keywords : ;

    Abstract : In this study, a macro-modeling strategy is implemented in a bearing wall with arch openings in an existing historical masonry building. This is to investigate what differences and similarities can be observed from the assumption of an orthotropic versus an isotropic constitutive material model. READ MORE

  5. 4. 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

  6. 5. Investigation of case hardened steel subjected to torsion: An experimental and numerical elastic-plastic material study

    University essay from KTH/Hållfasthetslära

    Author : Jonathan Fridstrand; [2022]
    Keywords : Torsion; Shear stress-strain relation; Elastoplastic material; Case hardened steel; Custom material model; Vridning; Skjuvtöjning och -spänning; Elastiskt-plastiskt material; Sätthärdat stål; Anpassad materialmodell;

    Abstract : There is currently a knowledge gap regarding the plastic material properties of many steel types that Atlas Copco use in their high torque power tools. This makes it difficult to fully utilise the capabilities of the Finite Element Method (FEM) to aid the developmental process. READ MORE
