1. 1. Influences of the Graphite Phase on Elastic and Plastic Deformation Behaviour of Cast Irons

   Författare :Torsten Sjögren; Ingvar L. Svensson; Sten Johansson; Jorge Sikora; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast iron; Flake graphite; Compacted graphite; Spheroidal graphite; Elastic deformation; Plastic deformation; Modulus of elasticity; Graphite modulus of elasticity; Strength coefficient; Strain hardening exponent; Acoustic emission; Construction materials; Konstruktionsmaterial;

   Sammanfattning : The amount and morphology of the graphite phase largely controls the resulting properties of cast iron. For instance, in flake graphite cast irons the mechanical properties are low while the thermal conductivity is high. LÄS MER

3. 2. 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

4. 3. Mechanical Characterisation of Coatings and Composites-Depth-Sensing Indentation and Finite Element Modelling

   Författare :Zhi-Hui Xu; KTH; []
   Nyckelord :dept-sensing indentation; nanoindentation; finite element method; atomic force microscope;

   Sammanfattning : In the past two decades depth-sensing indentation has becomea widely used technique to measure the mechanical properties ofmaterials. This technique is particularly suitable for thecharacterisation of materials at sub-micro or nano scale thoughthere is a tendency to extend its application to the micro ormacro scale. LÄS MER
