  1. 1. A Methodology for Evaluating the Performance of Material Models Under Biaxial Loads

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Emmie Salomonsson; Ina Ögren; [2023]
    Nyckelord :Material Model; Biaxial Test; Punch Test; Material Test; POM; Simulation; FEA.; Technology and Engineering;

    Sammanfattning : The objective of this thesis is to develop a methodology for evaluating the performance of material models during biaxial loads. This is done by executing identical punch tests, one in a simulation and one in a physical experiment, and then comparing the results from the two. LÄS MER

  3. 2. Method Development & Analysis of Seals using FEM

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lovisa Svanborg Östlin; [2023]
    Nyckelord :FEM; guidelines; hyperelastic materials; hyperelastic material models; method development; seals; FEM; riktlinjer; hyperelastiska material; hyperelastiska materialmodeller; metodutveckling; tätningar;

    Sammanfattning : Hyperelasticity is a significant property of rubber, taken advantage of in engineering applications. A common application is the use of seals to prevent fluid transfer (liquid or gas) between solid regions. Volvo CE is often depending on external supplier when developing seals. LÄS MER

  4. 3. Validation of An Iteration Free Material Model for Paperboard (NEO)

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Samuel Thomas Staines; [2022]
    Nyckelord :Paperboard; orthotropic; Constitutive equilibrium free; Non-linear; Curve fit constitutive relation; switch-wise history dependence; total formulation; explicit constitutive relation; In-plane; Elastic-plastic; Technology and Engineering;

    Sammanfattning : The NEO model, developed by Lindström (2019) for paperboard, is a non-linear material model that utilizes empirically based constitutive relations with switches to mimic elastic-plastic responses. Due to the explicit definition of the constitutive relations, the NEO model does not require a constitutive equilibrium loop. LÄS MER

  5. 4. Understanding the correlation between molecular structure of chilled dairy creams and the risk of environmental stress cracking in Tetra Pak® carton packages

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Alejandra Fernandez Castaneda; [2022]
    Nyckelord :Cream; microestructure; environmental stress cracking; food technology and nutrition; Agriculture and Food Sciences;

    Sammanfattning : Multilayer food packaging are lined with an inner layer of plastic and has excellent barrier properties. However, plastics lose their mechanical properties after being exposed to certain conditions; the combination of factors generates failures in the material such as the appearance of cracks, this phenomenon is known as environmental stress cracking (ESC).

  7. 5. Friction and material modelling in Sheet Metal Forming Simulations

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Herman Bentsrud; [2020]
    Nyckelord :Sheet metal forming; Material model; Triboform; Autoform; Plåtmetalformning; Materialmodell; Triboform; Autoform;

    Sammanfattning : In today’s car manufacturing industry, sheet metal forming is a important process that takes preparation, which is time consuming and complex when new processes are made. When new metal grades and alloys are provided to the industry, tests are conducted to determine it’s behaviour and strengths. LÄS MER
