  1. 1. Simultaneous Topology and Material Optimization of Composite Structures under Uncertainty

    Författare :Dženan Hozić; Carl-Johan Thore; François-Xavier Irisarri; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Optimization; Composite Structures; Topology Optimization; Multi-material Optimization; Material Uncertainty; Robust Optimization; Composite Structure Optimization; Design Optimization; Composite Material;

    Sammanfattning : Composite materials are known to have superior stiffness and strength properties per unit weight compared to metallic materials. These properties and the ability to tailor the mechanical properties of composites is the main motivation for choosing composite materials for structural components. LÄS MER

  3. 2. Failure prediction of orthotropic Non-Crimp Fabric reinforced composite materials

    Författare :Henrik Molker; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Orthotropic; Non crimp-fabric; Failure initiation; Design methodology; Carbon fibre composite;

    Sammanfattning : The automotive industry needs to reduce the energy consumption to decrease the impact on the environment. One part of this is to reduce the weight of cars, thereby reducing the fuel consumption. A promising way to be successful with this is to introduce carbon fibre composites in the structural parts.
