  1. 1. Efficient FE Modeling of Large Casted Parts

    Master-uppsats, KTH/Maskinkonstruktion

    Författare :Lalitha Swetha Amirapu; Haswanth Yalamanchili; [2023]
    Nyckelord :FE modeling; Large casted parts; Meshing techniques; Mid-surface modeling; FE-modellering; Stora gjutna delar; Meshing-tekniker; Mid-Surface modellering;

    Sammanfattning : The design and analysis of large casted parts present significant challenges due to their complex geometry. Finite Element (FE) modeling is a vital tool for understanding the performance of casted components. However, the computational requirements associated with these parts often lead to excessive processing times and resource utilization. LÄS MER

  3. 2. Tillämpning av set based dimensionering för optimering av påldäck : Vilken komplexitet och detaljnivå behövs

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Axel Jonzon; Viktor Alenbro; [2023]
    Nyckelord :Betongkonstruktion; pålar; påldäck; Grasshopper; parametrisk optimering; FE-Modellering; armeringsutformning; FEM-Design; klimatoptimering; byggbarhet;

    Sammanfattning : Behovet av att minska klimatpåverkan genom optimering av armerade betongkonstruktioner har på senaste årtiondet väckt stort intresse. I traditionell dimensionering av betongkonstruktioner övervägs endast ett fåtal utformningar. LÄS MER

  4. 3. Linear Impact of Bicycle Helmet – Experimental Testing and FE-modelling

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Ludvig Dahlin; Ebba Larsson Regnström; [2022]
    Nyckelord :FEM; Finite element method; bicycle helmet; impact modelling; solid mechanics; FEM; Finita element-metoden; cykelhjälm; islagsmodellering; hållfasthetslära;

    Sammanfattning : The aim with this master thesis was to set up a FE-simulation of an impact test of a bike helmet in LS-DYNA that correlates well with the peak acceleration score of a real life impact test. Furthermore, a parametric study has been performed in LS DYNA to investigate the robustness of the model, as well as to see which parameters have a great influence on the peak acceleration score.

  5. 4. Operational modal analysis and finite element modeling of a low-rise timber building

    Master-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Viktor Petersson; Andreas Svanberg; [2021]
    Nyckelord :Timber structure; Dynamic behavior; Operational modal analysis; FE-modeling; Mode shape; Natural frequency.; Träbyggnad; Dynamiskt beteende; Operational modal analysis; FE-modellering; Egenmod; Egenfrekvens.;

    Sammanfattning : Timber is a building material that is becoming more common and of interest for use in high-rise buildings. One of the reasons is that timber requires less energy input for the manufacturing process of the material compared to non-wood based materials. LÄS MER

  7. 5. FE-Modelling of a Joint for Cross-Laminated Timber

    Master-uppsats, Karlstads universitet/Avdelningen för maskin- och materialteknik

    Författare :Linus Ekhagen; [2021]
    Nyckelord :cross-laminated timber; fe-modelling; continuum damage mechanics; fracture; korslimmat trä; fe modellering; skademekanik; brott;

    Sammanfattning : Woodbe Engineering AB is a freshly started company that has developed a new type of joint for cross-laminated timber (CLT). The joint does not include any metallic fasteners, which improves sustainability, the ergonomics for the workers and time efficiency. LÄS MER
