  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. Verification of elastomer characteristics in electro-mechanical linear actuator

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

    Författare :Rohit Karmungikar; [2022]
    Nyckelord :ANSYS; Aging; Hyperelastic; MATLAB and Mooney-Rivlin; ANSYS; Åldrande; Hyperelastic; MATLAB och Mooney-Rivlin;

    Sammanfattning : Cascade Drives develops electromechanical actuators using a rack and pinion configuration to achieve a combination of high load and high-speed operation. A patented load distribution mechanism enables the use of multiple pinions on a single rack, resulting in a compact unit with high positional accuracy capable of absorbing shock loads. LÄS MER

  4. 3. Machine learning for constitutive modeling

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Anna Robbins; Gustav Vittberg; [2021]
    Nyckelord :;

    Sammanfattning : Constitutive modeling of nonlinear materials is a computationally complex and time-intensive process. To mitigate this, a neural network was used to simulate complex behaviors of non-linear materials. With supervised learning the machine learning model was able to predict the stresses in a material when given the strains. 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. Material Properties of Adhesive Joint

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Shuyue Wang; [2020]
    Nyckelord :;

    Sammanfattning : The development of the commercial 5G network with high-frequency mmWave requires tighter base station grid, which increases the demand for smaller and more unobtrusive products. One way to connect materials of different properties and keeping the product size small is to use adhesive joints instead of screw joints. LÄS MER
