  1. 1. Material characterization of long-term stress relaxation in a semi-crystalline polymer material : An experimental and numerical study

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola

    Författare :Jakob Görtz; [2021]
    Nyckelord :Abaqus; MCalibration; PRF; HDPE; Stress relaxation; Long-term testing; Theoretical expressions; Material calibration;

    Sammanfattning : As the plastic and packaging industry is looking to increase the longevity of plastic products as well as recycling used material, there is a need to understand how material properties respond and change during long periods of mechanical loading. Physical tensile experiments on thin plant-based High-Density Polyethylene (HDPE) are conducted with the intent of capturing relaxation behavior from a short-term (1-3 hours) and long-term (29-56 days) perspective.

  4. 3. Convergence Rate of the Dirichlet-Neumann Algorithm for Coupled Poisson Equations

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Morgan Görtz; [2019]
    Nyckelord :Dirichlet-Neumann; Dirichlet-Neumann algorithm; Poisson equation; convergence rate; finite element method; finite volume method; finite difference method; Mathematics and Statistics;

    Sammanfattning : This thesis presents and tests the convergence rate of the Dirichlet-Neumann algorithm for two Poisson equations coupled by transmission boundary conditions. Three second order discretisation methods are used when analyzing the convergence: standard equidistant finite difference, standard adaptive linear finite element, and standard adaptive finite volume discretisation of Poisson's equation.

  7. 5. Kassarna sprids med vinden, informationen ligger i lä: en studie av informationsflödet vid den svenska implementeringen av EU:s direktiv om plastbärkassar

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Lisa Elenström; Astrid Görtz; [2017]
    Nyckelord :plastic carriers; ocean pollution; consumers; Sweden; Earth and Environmental Sciences; Law and Political Science;

    Sammanfattning : Plastic carrier bags are one of the most frequently littered objects. They tend to accumulate in the oceans, posing a threat to marine organisms and birds which mistake them for food. To tackle this environmental issue, the EU has decided to reduce the consumption of plastic carrier bags through an amending directive. LÄS MER
