  1. 31. Hydraulic power steering in passenger cars : analysis, modeling and new functionality

    Författare :Marcus Rösth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : THIS THESIS COVERS various aspects of hydraulic power assisted steering, HPAS, systems in road vehicles. Power steering is viewed as a dynamic system and is investigated with linear and non-linear modeling techniques. LÄS MER

  3. 32. On large strain theories in sheet metal forming : general theories and numerical considerations with particular emphasis on strain analysis, non-conservative loading and plastic anisotropy

    Författare :Bo Ekmark; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Sammanfattning : The fundamentals of continuum mechanics in large strain problems are treated and analysed. Special emphasis is directed to strain analysis in large deformation problems and a comparison between the different types of strain terms is made. LÄS MER

  5. 34. Structural Analysis Methods for the Assessment of Reinforced Concrete Slabs

    Författare :Jiangpeng Shu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bridge Deck; Finite Element FE Analysis; Shear and Punching; Structural Response; Reinforced Concrete Slabs; Multi-level Assessment Strategy;

    Sammanfattning : Reinforced concrete (RC) slabs are among the most critical parts of the load-carrying capacity of such structures as bridges and parking decks. Previous research indicated that the assessment methods used in current practices largely underestimated the load-carrying capacity. LÄS MER
