  2. 2. Robust optimisation of structures : Evaluation and incorporation of variations in simulation based design

    Författare :David Aspenberg; Larsgunnar Nilsson; Kjell Simonsson; Niels Olhoff; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis concerns the robustness of structures considering various uncertainties. The overall objective is to evaluate and develop simulation based design methods in order to find solutions that are optimal both in the sense of handling typical load cases and minimising the variability of the response, i.e. robust optimal designs.

  3. 3. Ductile Failure in High Strength Steel Sheets

    Författare :Oscar Björklund; Larsgunnar Nilsson; Odd-Geir Lademo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Developments in computer-aided engineering and the rapid growth of computational power have made simulation-driven process and product development efficient and useful since it enables detailed evaluation of product designs and their manufacturing processes. In the context of a sheet metal component, it is vital to predict possible failure both during its forming process and its subsequent usage. LÄS MER

  4. 4. Modelling of Failure in High Strength Steel Sheets

    Författare :Oscar Björklund; Larsgunnar Nilsson; Odd Geir Lademo; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : In this theses the high strength steel Docol 600DP and the ultra high strength steel Docol 1200M are studied. Constitutive laws and failure models are calibrated and veried by the use of experiments and numerical simulations. LÄS MER
