  4. 8. Towards energy-based fracture modelling for crashworthiness applications

    Författare :Simon Jonsson; Jörgen Kajberg; Stefan Golling; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

    Sammanfattning : The automotive industry is currently adapting to progessively more stringent emission and safety regulations imposed by governmental agencies. This introduces significant design difficulties due to the conflicting nature of passenger safety in automotive manufacturing, namely that increased crashworthiness generally leads to heavier vehicles, which in turn leads to more severe crashes.

  5. 9. Foam modeling including pore gas interaction for crashworthiness analysis

    Författare :Mats L Landervik; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foams; Hyperelasto-viscoplasticity; Non-linear dynamics.; Staggered solution; Theory of Porous Media; Constitutive modeling;

    Sammanfattning : Foams are used in vehicles for three main functions: enhancing comfort, e.g.soft foams used in seats cushions, energy absorbtion, e.g. LÄS MER

  7. 10. Finite element simulation of airbag deployment and optimization in crashworthiness design

    Författare :Per-Olof Marklund; Göran Sandberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The passive safety of cars is of uttermost importance for the automotive industry. To improve the safety of cars, computer simulations of the vehicle and occupant system by the Finite Element Method (FEM), have become an industry standard tool. LÄS MER
