| Abstract Scope |
Numerical modelling can give insight into the evolution of microstructures under hot forming conditions. Cellular automata (CA) is a commonly used full-field method to simulate changes in microstructure morphology during different metal-forming processes. However, the CA method has some limitations related to computational domain geometry changes at high-temperature forming conditions. The use of random cellular automata (RCA) allows for a more realistic representation of this phenomenon. However, the RCA must be fully coupled with the finite element mesh in this case. The details of the developed coupled RCAFE model will be presented, including main assumptions and coupling strategies. The robustness analysis followed by the experimental validation of the developed model will also be discussed. |
