  1. 21. FINITE ELEMENT MODELING TO VERIFY RESIDUAL STRESS IN ORTHOGONAL MACHINING

    Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för maskinteknik

    Författare :CHANDRA SHEKHAR PRASAD; [2009]
    Nyckelord :FEM; ALE; ABAQUS;

    Sammanfattning : The aim of this thesis paper, to create a numerical model to examine the residual stresses induced by orthogonal machining in the finished work piece and the model is validated by comparing with experimental result. The finite element method is used to simulate and analyze the residual stresses induced by a orthogonal metal cutting process. LÄS MER

  3. 22. Numerical analysis of silo discharge

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :John Brown; [2008]
    Nyckelord :Inner tube; Iron ore pellets; Silo; Granular flow; FEM; ABAQUS.; Technology and Engineering;

    Sammanfattning : A silo discharge with a bulk material consisting of iron ore pellets is studied. The silo is about 65 meters high and 38 meters wide. The quality of pellets decreases when they are exposed to high stresses while moving. The stresses are therefore not allowed to exceed a certain threshold. LÄS MER

  4. 23. Evaluation of an Interphase Element using Explicit Finite Element Analysis

    Kandidat-uppsats, Institutionen för teknik och samhälle

    Författare :Daniel Svensson; Tomas Walander; [2008]
    Nyckelord :Explicit finite element analysis; double cantilever beam; end notched flexure; critical time step;

    Sammanfattning : A research group at University of Skövde has developed an interphase element for implementation in the commercial FE-software Abaqus. The element is using the Tvergaard & Hutchinson cohesive law and is implemented in Abaqus Explicit version 6.7 using the VUEL subroutine. LÄS MER

  5. 24. Analysmetoder för rörsystem

    Master-uppsats, Institutionen för ekonomisk och industriell utveckling

    Författare :Erik Holmberg; [2008]
    Nyckelord :rör; bockning; ovalitet; godsförtunning; spänningsanalys; kollaps; FEM; Finita elementmetoden; Abaqus; implicit; explicit;

    Sammanfattning : The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.

  7. 25. Optimering av balktvärsnitt med avseende på bärförmåga

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Byggnadsmekanik

    Författare :Sara Mattsson; [2004]
    Nyckelord :Technology and Engineering;

    Sammanfattning : SSAB Tunnplåt AB manufactures high strength steel to e.g. beams to trailers, containers, trucks and cars. In high strength steel designs the ratio width to thickness is also high and therefore the risk for local buckling is high. LÄS MER
