  2. 2. Tribological characterisation of additively manufactured hot forming steels

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Anna Vikhareva; [2020]
    Nyckelord :High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

    Sammanfattning : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. LÄS MER

  3. 3. Relation Between the Material in Press Hardening Dies and Fully Martensitic Transformation : Sheet properties of thick 3D-sheets in small series production

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

    Författare :Jesper Christensson; [2020]
    Nyckelord :hot stamping; press hardening; material properties;

    Sammanfattning : This report evaluates the influence of the die material on the cooling rate and martensitic transformation of press hardened sheets. The goal was to increase the thicknesses of sheets that can form fully martensitic microstructure when press hardened. LÄS MER

  4. 4. Extraction of tool reaction forces using LS-DYNA and its use in Autoform sheet metal forming simulation

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Esbjörn Zachén; [2019]
    Nyckelord :Sheet Metal Forming; Stamping Die; blank holder; Structural Analysis; Finite Element Simulation;

    Sammanfattning : In product development there is still potential to decrease lead times with faster and more accurate simulations. The objective of this thesis was to study whether Finite Element (FE) simulations using explicit LS-DYNA to extract reaction forces from sheet metal forming tools during forming, could be used to improve existing FE models in sheet metal forming software AutoForm.

  5. 5. FE Modeling of Cushion 3D Motion for Sheet Metal Forming Simulation

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Jagdish Jadhav; [2019]
    Nyckelord :Finite Element analysis; contact pressure; sheet metal forming; LS-DYNA.;

    Sammanfattning : Nowadays FE-simulations for sheet metal forming process are used to reduce the tryout phase in automotive industries. But the complex forming simulation processes are very challenging. One of the challenges is to create an FE-model which can be used to analyze the effects of cushion motion on the forming process.
