  1. 1. Elastoplasticity of Grey Cast Iron FE-Algorithms and Biaxial Experiments

    Author : Hans E. Hjelm; Chalmers University of Technology; []
    Keywords : Biaxial experiments; multiaxial elastoplastic behaviour; graphite flakes; FE-codes; hardening behaviour; graphitic grey cast iron;

    Abstract : This thesis focuses on multiaxial elastoplastic behaviour of graphitic grey cast iron with the aim to provide physically appropriate and numerically reliable constitutive relations for use in FE-codes. To achieve this goal, this work is divided into three parts: Biaxial experiments are performed on thin cruciform specimens. READ MORE

  2. 2. Microstructure Formation During Solidification and Solid State Transformation in Compacted Graphite Iron

    Author : Mathias König; Magnus Wessén; Ingvar L. Svensson; Jorge Sikora; Chalmers University of Technology; []
    Keywords : Solidification; Solid state transformation; Modelling; Mechanical properties; Cast iron; CGI; Microstructure formation; Cast Iron; Microstructure Formation; Mechanical Properties; Solid State Transformation;

    Abstract : Compacted graphite iron (CGI) is rapidly becoming an attractive alternative material for engine components in the automotive industry, replacing lamellar graphite iron (LGI) in applications where high mechanical strength is desired. However, the gain in mechanical strength comes with a cost; thermal conductivity, process control and machining are three areas that are more challenging for CGI. READ MORE
