  3. 12. Dendritic morphology and ultimate tensile strength of pearlitic lamellar graphite iron

    Författare :Vasilios Fourlakidis; Attila Diószegi; Carlos A. Silva Ribeiro; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lamellar graphite iron; Primary austenite dendrite; Ultimate tensile strength; Microstructure model;

    Sammanfattning : The continued development, of cylinder blocks and cylinder heads for heavy truck engines that are made of lamellar graphite iron (LGI) is focused on achieving high ultimate tensile strength (UTS) whilst conforming to environmental regulations. The purpose of this work is to further improve the tensile strength as well as the predictive engineering tools for optimization of LGI aimed to enhance the efforts for producing lighter and sustainable components without sacrificing performance.

  4. 13. Microstructure and deformation behaviour of ductile iron under tensile loading

    Författare :Keivan Amiri Kasvayee; Anders E.W. Jarfors; Ehsan Ghassemali; Lennart Elmquist; Kenneth Hamberg; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ductile iron; digital image correlation DIC ; in-situ tensile test; pit etching; Microscale deformation; micro-crack; finite elements analysis FEA ; cohesive elements;

    Sammanfattning : The current thesis focuses on the deformation behaviour and strain distribution in the microstructure of ductile iron during tensile loading. Utilizing Digital Image Correlation (DIC) and in-situ tensile test under optical microscope, a method was developed to measure high resolution strain in microstructural constitutes. LÄS MER

  7. 15. A theory of bond applied to overlapped tensile reinforcement splices for deformed bars

    Författare :Ralejs Tepfers; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete; splitting failures; confinement; deformed bars; tensile overlap splices; bond theory; fatigue; concrete cover splitting; reinforcement;

    Sammanfattning : A bond theory for deformed reinforcing bars in concrete is elaborated taking into account different stages in development of final rupture occurring as splitting or pull-out. The concrete cover splitting resistance is modelled for a thick-walled concrete ring in elastic and plastic stages. Different final possible failure modes are analysed. LÄS MER
