  1. 6. 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. 7. Investigation of methods to analyse global stability of a reinforced concrete stabilising core

    University essay from KTH/Bro- och stålbyggnad

    Author : Evelina Husak; Ellinor Persson; [2022]
    Keywords : ;

    Abstract : Ensuring the structural stability of a building is an evident requirement for the building to be safe to use. This becomes a qualified task for a structural engineer. Ensuring stability has become especially important nowadays while stabilising elements often are kept to a minimum and tall buildings are common. READ MORE

  4. 8. Design of passively loaded specimen for constant KI during crack growth

    University essay from KTH/Hållfasthetslära

    Author : Liisa Tofferi; [2021]
    Keywords : constant KI; passively loaded specimen; konstant KI; passivt belastad provstav;

    Abstract : Passive loading of a specimen is a relatively cheap method to use in fracture mechanical testing compared to an actively loaded specimen. For stress corrosion cracking testing it is easier to use a passively loaded specimen since the specimen easily can be placed in a specific corrosive environment. READ MORE

  5. 9. CHARACTERISATION OF CROSS LAMINATED TIMBER PROPERTIES

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

    Author : Emil Nilsson; [2021]
    Keywords : CLT; cross laminated timber; in-plane loading; out-of-plane loading; beam; rolling shear modulus; experimental tests; FE-modelling; Technology and Engineering;

    Abstract : This project concerns an analysis of a hitherto untested method for determining the modulus of elasticity (MoE) and shear modulus parallel to grain, as well as the rolling shear modulus of cross laminated timber (CLT) through 3-point bending tests. A review of analytical models and methods is included, followed by an evaluation of the effect of the annual ring orientation and shear stress distribution at shear loading of individual board cross-sections.

  6. 10. Machine learning for constitutive modeling

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Anna Robbins; Gustav Vittberg; [2021]
    Keywords : ;

    Abstract : Constitutive modeling of nonlinear materials is a computationally complex and time-intensive process. To mitigate this, a neural network was used to simulate complex behaviors of non-linear materials. With supervised learning the machine learning model was able to predict the stresses in a material when given the strains. READ MORE
