2. 1. Anisotropy in pearlitic steel subjected to rolling contact fatigue - modelling and experiments

   Author : NASIM LARIJANI; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pearlitic steel; crack propagation; Rolling Contact Fatigue; Anisotropy; plasticity; High Pressure Torsion;

   Abstract : In rails and wheels subjected to severe rolling/sliding contact, large plastic deformations accumulate in the surface layer. This decreases the fatigue resistance of components and makes this layer prone to formation of common rolling contact related defects. READ MORE

4. 2. On the modeling of anisotropy in pearlitic steel subjected to rolling contact fatigue

   Author : NASIM LARIJANI; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rolling Contact Fatigue; crack propagation; Anisotropy; plasticity; pearlitic steel; material forces;

   Abstract : One of the main sources of damage caused by Rolling Contact Fatigue (RCF) inrailway components is the large plastic deformations that accumulate in the surface layerof these components. Large plastic deformations in components made of pearlitic steelinduce anisotropy in the mechanical properties of the material. READ MORE
