  1. 1. An investigation of the design of cylinderical steel tanks modelled according to EN14015 and according to the Eurocodes

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Yonas Gebre; [2022]
    Keywords : Keywords: Steel tank; Wind; Snow; FEM; Shell buckling; Non-linear analysis;

    Abstract : Abstract Storage tanks are above or below ground vessels for storing chemicals, petroleum and other liquid products. Above ground vertical cylindrical shells are typically thin walled structures prone to buckling and lose their stability especially when they are empty or have lower fluid level due to external loads.

  3. 2. Correlation-based analysis on thin walled tubes

    University essay from Jönköping University/JTH, Produktionsutveckling

    Author : Andreas Hedlund; Daniel Blom; [2022]
    Keywords : Thin-walled tubes; Crashworthiness; Energy absorption; Finite element method; Finite element method automation.;

    Abstract : In the transportation sector, crash structures are often used to protect their inhabitants inthe event of a collision. These crash structures frequently utilize thin-walled tubes as energyabsorbers. The process of developing thin-walled tubes is iterative based and requires mul-tiple simulations, making it resource intensive. READ MORE

  4. 3. Implementation and validation of an isogeometric hierarchic shell formulation

    University essay from KTH/Bro- och stålbyggnad

    Author : Michael Loibl; [2019]
    Keywords : Isogeometric Analysis; Shell; Locking; Kirchho-Love; Reissner-Mindlin; Three-Dimensional Shell I;

    Abstract : Within this thesis, thin walled shell structures are discussed with modern element formulationsin the context of the Isogeometric Analysis (IGA). IGA was designed to achieve a directinterface from CAD to analysis. According to the concept of IGA, Non-Uniform RationalB-Splines (NURBS) are used as shape functions in the design and the analysis.

  5. 4. Local Buckling of Doubly-Symmetric I-Sections Subjected to Warping Torsion : The limitations of the Reduced Cross-Section Method under unconventional loading

    University essay from KTH/Bro- och stålbyggnad

    Author : Miklós Ori; [2019]
    Keywords : Local plate buckling – Warping torsion – Finite element modelling - Eurocode;

    Abstract : In regular design practice, when it comes to conventional loading, such as uniaxial compression and bending, the local buckling of thin plates is taken care of through cross section classification. The effect of warping torsion, which also gives rise to normal stresses in the section, however, is typically not considered in the process. READ MORE

  6. 5. Tank Shell Design According to Eurocodes and Evaluation of Calculation Methods

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

    Author : Malin Pluto; [2018]
    Keywords : Tank; Eurocode; Membrane theory; Linear elastic shell analysis; Finite element method;

    Abstract : Tanks are storage vessels for liquids. They can have different appearances; some are short and wide, others are tall and slim, some are small, others are large. In this thesis a tank of 6 m in both diameter and height has been used to obtain numerical results of the stresses in the tank. READ MORE
