  1. 1. Numerical Modelling of Combined Forming and Punching of Sheet Metal for Heat Exchanger Applications

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

    Författare :Erik Stålbrand; [2023]
    Nyckelord :Solid Mechanics; Material Modelling; Damage Modelling; Sheet Metal Damage; Punching Simulation; Forming Simulation; Heat Exchanger; Technology and Engineering;

    Sammanfattning : In this work a strategy for numerical simulation of punching during concurrent pressing of stainless steel sheet metal has been investigated accounting for the stress triaxiality and Lode angle parameter. Modelling of the damage evolution of a sheet metal is a useful tool within the field of engineering and materials science, and can provide useful information regarding material capabilities in a design process.

    Nyckelord :hermoplastics; polyamide 6; yield criteria; uniaxial stress; compression test; triaxiality; Mohr’s Circle; Lode Parameter; LS-DYNA; ermoplaster; polyamid 6; flyttspänningskriterier; enaxlig spänning; kompressionsprov; triaxialitet; Mohrs Cirkel; Lode Parameter; LS-DYNA;

    Sammanfattning : The application of thermoplastics as load-carrying components in furniture applications is an attractive prospect at IKEA. Thermoplastics can be used instead of metal where advanced geometries and aesthetics are considered. LÄS MER

  4. 3. Numerical Simulation of Ductile Cast Iron Fracture : A parameterization of the material model *MAT_224 in the FE-code LS-DYNA

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Viktor Eriksson; [2015]
    Nyckelord :;

    Sammanfattning : In crashes, fracture of Ductile Cast Iron (DCI) components can have a big influence on the global behaviour of the structure and the survival probability of the driver. In this thesis the material model *MAT_224 is parameterized for one ferritic-pearlitic grade, SS-0727-02, of DCI. LÄS MER

  5. 4. Modelling of bolt fracture

    Master-uppsats, Linköpings universitet/Hållfasthetslära

    Författare :Michael von Rosen; [2014]
    Nyckelord :fracture; failure; bolt; Lode; triaxiality; LS-DYNA;

    Sammanfattning : Computer simulations are widely used in the truck industry in order to provide assistance in the product development. Bolt joints are common in trucks. A bolt fracture usually has a great influence on how a truck structure will behave in a crash. LÄS MER
