Метод синтетичного моделювання структури високоміцного чавуну з подальшим аналізом властивостей матеріалу

Abstract

In this work ductile iron with spherical graphite microstructure is estimate. The method of ductile iron structure synthesis according to the microstructure image is proposed. OpenCV image processing technology is used. Graphite inclusions found by contour search. Finite element model based on the information about the geometry of inclusions. The stress-strain state calculating with two-dimensional 8-node finite element of two degrees of freedom in the node. A system of linear algebraic equations of Elastic modulus, Poisson’s ratio and Shear modulus calculated. The obtained results correspond to the reference data. In the conclusion, the proposed method of ductile iron microstructure generation is correct and can be used for experiments and computer analysis.
