  1. 1. Non-Linear strain paths in Sheet Metal Forming

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

    Författare :Anton Eriksson; [2021]
    Nyckelord :Sheet metal forming SMF ; Non-Linear strain path NLSP ; Test procedures; Failure models; Finite Element FE ; Plåtformning; Icke-linjära töjningsbanor; Test procedurer; brott model; Finita Element FE .;

    Sammanfattning : Today's automotive requirements have resulted in complex Sheet Metal Forming (SMF) processes of Sheet Metal (SM) with reduced formability, and thus it is crucial to be able to predict formability accurately to prevent material failure during SMF. Formability predictions today utilize Forming Limit Curves (FLC)s in Finite Element Analysis (FEA), but  FLCs are not valid for the Non-Linear Strain Paths (NLSP)s generated during SMF. LÄS MER

  3. 2. Fracture prediction of stretched shear cut edges in sheets made of Dual-Phase steel

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Johannes Falk; [2017]
    Nyckelord :Strain; DP steel; Dual-phase steel; Autoform; Aramis; Fracture strain; Advanced High Strength Steels; AHSS; Fracture prediction;

    Sammanfattning : Dual-Phase (DP) steels, part of the group of Advanced High Strength Steels (AHSS), are used by car manufactures due to its large strength to weight ratio. The high strength of the DP steel does have a negative impact on the formability during sheet metal forming and stretch forming, e.g. LÄS MER

  4. 3. Finite Element Simulation of Crash Testing of Self-Piercing Rivet Joints, Peel Specimen

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Christian Westerberg; [2002]
    Nyckelord :Technology and Engineering;

    Sammanfattning : Within the automotive industry today, companies save significant amounts of money through computer simulations. Mathematics through numerical methods becomes important when as in this case the investigation is done with the Finite Element Method (FEM). A self-pierced rivet (SPR) joint specimen in a T-peel case is studied. LÄS MER
