Distribution of Stress around the Graphitic Particles in Cast Iron Microstructure

Abstract:

The given work is focused on the analysis of the distribution of stress around graphitic particles in microstructure of the ductile cast iron with the spheroidal shape of graphite (SGCI) and grey cast iron with the lamellar shape of graphite (LGCI). The analysis was made with help of finite element method in the software system ADINA.v.8.6.2. On the basis of the real structure, the finite element method was used for creation of the model which was subsequently used for calculation of the distribution of stress in the material structure. The input data for numerical analysis were obtained on the basis of evaluation of the structure by help of image analysis. The numerical analysis proved that the graphitic particles in the matrix cause the accumulation of the stress and the distribution of the given stress depends on the shape of the graphitic particles.
