  1. 1. 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

  3. 2. Fracture simulation with a hyperelastic phase field model

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Adrien Fradet; [2023]
    Nyckelord :Fracture; Phase field modeling; Hyperelasticity; Brott; fasfält-methoden; hyperelasticite;

    Sammanfattning : The phase field method is a versatile tool to study crack initiation and propagation in systems with complex geometries. Based on a variational formulation of the equilibrium equations, the sharp crack topology is regularized by a crack with diffusive edges and the damage is described by a continuous phase field variable.

  4. 3. Compression Characteristics of Elastomer Elements

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rahul Nagaraj Dixit; [2021]
    Nyckelord :Continuum mechanics; Hyperelasticity; Mooney Rivlin; Rack and Pinion; Kontinuummekanik; Hyperelasticitet; Mooney Rivlin; Kuggstångsväxel;

    Sammanfattning : Compression of elastomer elements are nonlinear due to the cross-linked molecular structure owing to a property known as hyperelasticity. Hyperelasticity is defined as the nonlinear stress-strain behavior shown by rubber like materials which can be strained up to a range of 700% in tension and up to 40% in compression. LÄS MER

  5. 4. Material Characterization for the Simulation of Drop Tests Against PMMA Sheets

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Arturo Sancho Montagut; [2020]
    Nyckelord :Abaqus; Polymers; PMMA; Acrylic; Simulation; Material Models; Hyperelasticity; Plasticity; Viscoelasticity; Drucker Prager; Yeoh; Drop Test; Luminaires;

    Sammanfattning : There is a high demand for implementing simulations in the design and product devel-opment processes, avoiding the execution of costly tests on prototypes and giving thechance of discarding unsuitable designs, as well as exploring possible ones without much cost added.This project assignment is to find a suitable way to simulate drop tests on two typesof PMMA sheets, a material widely used on luminaire covers.

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

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Jia Cheng Xu; [2019]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
