Computational Modeling of the Microplasticization State in the Nodular Cast Iron

The article deals with the creation of models for the analysis of plastic zones generation in ductile cast iron. The aim is the study of the microplasticization process near the graphite particles border. In creating the graphite particle model there is randomly chosen shape and orientation of the particle. The basic characteristic of the shape is ovality (the ratio of the inscribed circle to the circumscribed circle). The size of plastic deformation and the size of the plastic area are monitored by the microplasticization process analysis. The results are statistically elaborated to determine the relationship between graphite particle ovality and microplasticization caused by an inclusion.
