  1. 1. 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.

  3. 2. Virtual Material Testing of Adhesive Joints

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Vinit Jethalal Nagda; [2020]
    Nyckelord :;

    Sammanfattning : The automotive industry has shown an increasing interest in adhesive bonding for mixed-material joining. Modern design methods are critically dependent on accurate material models and data for numerical methods to enable the simulation of a design prototype early in the design process. LÄS MER

  4. 3. Numerical analysis of vibrations due to impact pile driving

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Sebastian Andersson Olivecrona; Rasmus Sulander; [2016]
    Nyckelord :Finite element method; Concrete pile; Impact pile driving; Ground vibrations; Soil mechanics; Soil dynamics; COMSOL Multiphysics; Technology and Engineering;

    Sammanfattning : Vibrations originating from constructional work can affect the nearby soil and structures. Depending on the properties of the vibrations, these can result in settlements in the soil and damages to existing structures. Along with blasting, impact pile driving is one of the greatest sources of vibrations on a construction site. LÄS MER

  5. 4. A deformable terrain model in multi-domain dynamics using elastoplastic constraints: An adaptive approach

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Simon Agvik; [2015]
    Nyckelord :deformable terrain model; real-time simulations;

    Sammanfattning : Achieving realistic simulations of terrain vehicles in their work environment does not only require a careful model of the vehicle itself but the vehicle's interactions with the surroundings are equally important. For off-road ground vehicles the terrain will heavily affect the behaviour of the vehicle and thus puts great demands on the terrain model. LÄS MER

  7. 5. Assessment of Finite Element Softwares for Geotechnical Calculations

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Geoteknik

    Författare :Alex Spetz; [2012]
    Nyckelord :Technology and Engineering;

    Sammanfattning : When building new constructions under ground level in cities it is important that the foundations of neighboring buildings are undisturbed. The regulations regarding soil deformations are hence very strict and conventional methods of predicting soil behavior is often too crude. LÄS MER
