  1. 1. Validation of Finite Element Model of a Tetra Pak Package

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Warsame Mohamed Ali; Abdullahi Abdi Hashi; [2023]
    Keywords : Abaqus; HDPE; Package testing; Validation; Abaqus; HDPE; Pakettestning; Validering;

    Abstract : There is a high dependency on accurate finite element models in the packaging industry for concept selection, design and virtual validation of packages. One of themost used materials for these packages is High-Density Polyethylene (HDPE). Thismaterial is highly anisotropic, strain rate dependent and has different behavior intension and compression.

  3. 2. Development of Methodology for Finite Element Simulation of Overhead Guard Impact Test

    University essay from Linköpings universitet/Mekanik och hållfasthetslära

    Author : Axel Hallén; Jacob Hjorth; [2022]
    Keywords : Explicit Finite Element Analysis; Forklift Overhead Guard; RADIOSS; Drop Test; Strain-Rate Sensitivity; Johnson-Cook; Plasticity; Explicit finita elementanalys; Skyddstak; Gaffeltruck; RADIOSS; Fallprov; Töjningshastighetsberoende; Johnson-Cook; Plasticitet;

    Abstract : Forklifts that are capable of lifting heavy loads and reaching high lift heights are required by stan-dards to have an overhead guard to protect the operator from falling objects. The same standardsspecify a standardized procedure for testing the strength of these overhead guards. READ MORE

  4. 3. Strain rate-dependent mechanical properties of high-density polyethylene(HDPE)

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Author : Oscar Andersson; Alexander Wiklund; [2022]
    Keywords : HDPE; strain rate; DIC; inverse calibration; Abaqus; HDPE; töjningshastighet; DIC; Inverskalibrering; Abaqus;

    Abstract : In today’s packaging industry HDPE is widely used and correct understanding of itsproperties and how to model them is of vital importance. HDPE is a semi-crystallinepolymer with a known strain rate dependence, that is a higher yield and lower strainto failure at higher strain rates. READ MORE

  5. 4. Evaluation of Thoracic Injury Risk of Heavy Goods Vehicle Occupants during Steering Wheel Rim Impacts to Different Rib Levels

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Jia Cheng Xu; [2019]
    Keywords : Heavy Goods Vehicles HGVs ; Rim Impacts; Human Body Models HBM ; Total HUman Model for Safety THUMS ; Hybrid III; ribs; aorta; liver; spleen; injury risk functions; material models; cumulative distribution function CDF ; Ogden; risk curves; Lastbilar; rattislag; humanmodeller; Total HUman Model for Safety THUMS ; Hybrid III; revben; aorta; lever; mjälte; riskfunktioner; materialmodeller; kumulativ fördelningsfunktion; Ogden; riskkurvor;

    Abstract : The interior of heavy goods vehicles (HGVs) differs from passenger cars. Both the steering wheel and the occupant are positioned differently in a HGV and increases the risk of steering wheel rim impacts. READ MORE

  6. 5. A finite element material modelingtechnique for the hysteretic behaviour of reinforced rubber

    University essay from KTH/Hållfasthetslära (Avd.)

    Author : Petter Lind; [2017]
    Keywords : ;

    Abstract : Reinforced rubber is thanks to its elastic and dissipative properties found in industrialapplications such as isolators, flexible joints and tires. Its dissipative propertied comes from material related losses which have the effect that energy invested when deforming the material is not retained when returning it back to its initial state.
