  1. 1. 4-Point Bending of Composite Laminates for FEM/FEA Validation

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Pierce Cashin; [2023]
    Nyckelord :composites; 4-point bending; fiberglass; sandwich panel;

    Sammanfattning : When designing structures and vehicles using composite materials, engineers need access to critical information regarding the composite materials in question. This information describes the strength, stiffness, failure mode, and other variables that can be used to properly determine how a structure will perform while undergoing various loads and effects.

  3. 2. Enhancing failure prediction from timeseries histogram data : through fine-tuned lower-dimensional representations

    Master-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Vijay Jayaraman; [2023]
    Nyckelord :time-series prediction; time-series histogram analysis; Convolution Neural Network CNN ; Autoencoder; Weibull Time-to-Event WTTE ; Recurrent Neural Network RNN ; Engine turbo charger failure prediciton;

    Sammanfattning : Histogram data are widely used for compressing high-frequency time-series signals due to their ability to capture distributional informa-tion. However, this compression comes at the cost of increased di-mensionality and loss of contextual details from the original features. LÄS MER

  4. 3. A viscoelastic evaluation of an injectable disulfide cross-linked thiol-collagen hydrogel: for tissue bulking post-myocardial infarction to prevent heart failure

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Makromolekylär kemi

    Författare :Karin Dungner; [2023]
    Nyckelord :;

    Sammanfattning : Cardiovascular diseases are currently the leading cause of death globally. Progression of the disease affects the composition and function of the heart and in many cases subsequently results in heart failure over time where a heart transplant is vital. Therefore, there is a need for medical treatments to stop the progression of the disease. LÄS MER

  5. 4. FE-modelling of glulam connection in a pre-tensioned glulam truss : Detailed Finite element modelling of the connection between primary beam and compression stud in a sub-tensioned glulam roof truss

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Edward Sebastian Swaretz; [2022]
    Nyckelord :Glulam; sub-tensioned roof truss; connection; instability; Abaqus Standard; Finite element method;

    Sammanfattning : After the collapse of the roof structure in Tarfalahallen 2020, great attention has been focused on instability of sub-tensioned glulam roof trusses. Investigations were launched to find the reason for the collapse and the cause was instability in the roof truss that supported the roof. LÄS MER

  7. 5. FEM Analysis of paperboard packaging

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Wen-Che Li; [2022]
    Nyckelord :;

    Sammanfattning : The work aims to provide a finite element model using Ansys Workbench for realistically simulating paperboard packages. The geometrical properties of a package and the loading conditions were altered to investigate their influence on the box behavior and the applicability of Ansys as the finite element solver for paperboard material.
