  2. 1. Plastic behaviour of steel : experimental investigation and modelling

    Author : Jonas Gozzi; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Abstract : This thesis deals with the plastic behaviour of steel. It comprises an investigation with focus on biaxial tests and constitutive modelling. Tests were performed on one stainless steel grade in two different strength classes, C700 and C850, as well as one extra high strength structural steel grade. READ MORE

  5. 3. Micro-mechanical FE-simulations of the plastic behaviour of steels undergoing martensitic transformation

    Author : Kjell Simonsson; Sören Sjöström; Marcel Berveiller; Linköpings universitet; []
    Keywords : Steel; martensitic transformation; grain constitution; finite element simulations; plastic behaviour; transformation kinetics; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis is concerned with the mechanical behaviour of steels undergoing martensitic transformation. More specifically, the aim has been to develop a method to numerically stimulate the mean strain (or stress) response associated with a prescribed temperature and mean stress (or strain) variation.

  6. 4. Modelling and simulation of plastic deformation on small scales : interface conditions and size effects of thin films

    Author : Per Fredriksson; Peter Gudmundson; Christian Niordson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strain gradient plasticity; Size effects; Thin films; Interface; Finite element method; Dislocations; Constitutive behaviour; Hardening behaviour; Indentation; Contact mechanics; Metal matrix composites; Engineering mechanics; Teknisk mekanik;

    Abstract : Contrary to elastic deformation, plastic deformation of crystalline materials, such as metals, is size-dependent. Most commonly, this phenomenon is present but unnoticed, such as the effect of microstructural length scales. READ MORE

  7. 5. The influence of graphite morphology on the elastic behaviour of cast irons

    Author : Torsten Sjögren; Linköpings universitet; []
    Keywords : Cast iron; flake graphite; compacted graphite; spheroidal graphite; elastic behaviour; modulus of elasticity; graphite modulus of elasticity; nodularity; aspect ratio; plastic deformation; acoustic emission; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The morphology of the graphite phase largely controls the resulting properties of different grades of cast iron. In flake graphite cast irons, the mechanical properties are low while the thermal conductivity is high. In contrast, with spheroidal graphite cast irons, the mechanical properties are high while the thermal conductivity is low. READ MORE
