  1. 1. A comparative evaluation of hydrostatic pressure and buckling of a large cylindrical steel tank designed according to EN14015 and according to the Eurocodes

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Musole Kambita; [2022]
    Keywords : Cylindrical steel tanks; yield strength; carbon steel; high strength steel; design load; buckling; stiffening rings; Finite Element Method FEM ; Linear Elastic Bifurcation LBA ; and Geometrically and Materially Nonlinear Analysis with Imperfections GMNIA .;

    Abstract : Above ground steel storage tanks are used worldwide for the storage of various liquids. EN 14015:2005, which has traditionally been used to design the tanks, does not necessarily fulfil the requirements of the Swedish Building Code. READ MORE

  3. 2. Conservative high order collocation methods for nonlinear Schrödinger equations

    University essay from Stockholms universitet/Fysikum

    Author : Pau Riera; [2021]
    Keywords : Gross-Pitaevskii equation;

    Abstract : In this thesis, we investigate the numerical solution of time-dependent nonlinear Schrödinger equations (more specifically, the Gross-Pitaevskii equation) that appear in the modeling of Bose-Einstein condensates. Since the model is known to conserve important physical invariants, such as mass and energy of the condensate, our goal is to study the importance of reproducing the conservation on the discrete level.

  4. 3. Reinforcement Layout in Concrete Pile Foundations : A study based on non - linear finite element analysis

    University essay from KTH/Betongbyggnad

    Author : Mohammad Mustafa Angar; [2020]
    Keywords : Pile cap; Nonlinear finite element analysis; ATENA 3D; Reinforcement layout; Strut and tie method; Pålfundament; icke-linjära finita elementmodeller; strut and tie-metoden;

    Abstract : The main topic of this thesis concerns the behavior of concrete pile cap supported by four piles with two varying positions of longitudinal reinforcements. The positions include top of piles and bottom of the pile cap. For this purpose, non-linear finite element models of a pile cap are created using software ATENA 3D. READ MORE

  5. 4. Development of a method for estimation of contact fatigue life in hypoid gears

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Srigiripura Sahana Vittal; [2020]
    Keywords : Hypoid Gear; Rolling Contact fatigue; Fatigue life; FEM; Gear Contact life; Spalling; physical testing; fatigue analysis; Hypoidväxel; rullande kontaktutmattning; utmattningslivslängd; FEM; växelkontaktlivslängd; spalling; fysisk testning; utmattningsanalys;

    Abstract : Hypoid gears have been used extensively in automobiles, aerospace, marine and other applications for decades. The special advantages of hypoid gears come with inherent contact complexities of varying curvature and sliding in both profile and lengthwise direction. READ MORE

  6. 5. Dynamic Analysis of an Automotive Power Transfer unit : Towards prediction of TE and housing vibrations

    University essay from KTH/Maskinkonstruktion (Avd.)

    Author : Nikhil Maharshi Kosaraju; [2019]
    Keywords : Power transfer unit PTU ; Multi-Body Simulation MBS ; Transmission Error; Gear NoiseVibration; Modal Analysis; Vinkelväxlen PTU ; Multi-Body Simulering MBS ; transmissionsfel TE ; Växelljud och vibrationer; Modal analys;

    Abstract : This work describes the use of Multi-Body Simulation (MBS) to create a virtual prototype of a geared drive called Power transfer unit (PTU). PTU is a subsystem of the all-wheel drive driveline responsible for transfer of power between front and rear axles in an Automobile. READ MORE
