  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. Adaptive Clay Formations

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

    Author : Anton Johansson; Edurne Morales Zúñiga; [2021]
    Keywords : digital fabrication; clay; clay construction; earthen construction; construction robotics; path planning; mobile robotics; computational design; robotics; non-linear fabrication; Arts and Architecture;

    Abstract : Rapid Clay Formations (RCF) is an ongoing research project investigating robotic aggregation of soft clay elements. This thesis presents our research into RCF construction on an architectural scale. It outlines our development of a fabrication process suitable for the construction of tall and slender structures made out of clay. READ MORE

  4. 3. Negative energy elasticity and a model for the behavior of the residual strain in doubly cross-linked gels fabricated by shear strain

    University essay from Uppsala universitet/Polymerkemi

    Author : Therese You; [2020]
    Keywords : Polymer gel; Tetra-PEG; hydrogels; doubly cross-linked gels; shear modulus; energy elasticity;

    Abstract : Doubly cross-linked gels were fabricated based on tetra-poly(ethylene glycol) (Tetra-PEG) by shear strain. These are gels with two network structures present in the same polymeric network. The second network structure is introduced by applying a mechanical field to the first natural network structure.

  5. 4. Electrical Characterizationon Commercially Available Chemical Vapor Deposition (CVD) Graphene

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Mikael Anttila-Eriksson; [2016]
    Keywords : GFET; Graphene; Dirac point shift; Charge carrier mobility;

    Abstract : Field-effect transistors (FET) based on graphene as channel has extraordinaryproperties in terms of charge mobility, charge carrier density etc. However, there aremany challenges to graphene based FET due to the fact graphene is a monolayer ofatoms in 2-dimentional space that is strongly influenced by the operating conditions.

  6. 5. A simplified forging simulation tool: validation with finite element method

    University essay from Institutionen för teknik och samhälle

    Author : Omar Zini; [2013]
    Keywords : ;

    Abstract : Nowadays, the forging industry has a great importance in the fabrication of metallic parts. Therefore, new theoretical models, or modifications to others already existing, continuously appear to improve the process. New investigations culminated, recently, in equations designed to obtain the necessary pressure to forge a part. READ MORE
