Evolution of microstructure during the shape rolling modeled by cellular automata

摘要

The numerical modeling of micro structure evolution in the forming processes is used different schemes and different tools. One of the methods is cellular automata (CA), and recently an interest in cellular automata for modeling of forming processes is increased constantly. Cellular automata are considered as one of the most optimal tool for microstructure modeling because of the computational effort and the obtained results. The paper presents the use of frontal cellular automata (FCA) for modeling microstructure evolution during the rolling process. The use of frontal cellular automata in combination with other methods is related to the possibility of obtaining more accurate and reliable results and has undeniable advantages. Results of the modeling of the process by finite element method (FEM) are input data for further simulation by FCA. Some examples of microstructure as results of FCA simulation are presented in the paper.
