Development of the cellular automata framework dedicated for metallic materials microstructure evolution models

Rauch L., Madej L., Spytkowski P., Golab R.

Archives of Civil and Mechanical Engineering

2015

Vol. 15, no. 1

48--61

The main goal of the paper is to design and implement a framework based on the cellular automata (CA) method, which is dedicated to numerical simulations of microstructure evolution in metallic materials under thermal and mechanical processing. Major assumptions and implementation details of the proposed solution involving classes containing dedicated fields and methods are discussed. Finally, the cellular automata framework (CAF) is tested for selected case studies supported by the Windows Workflow Foundation (WWF) approach. Particular attention is put on modelling simple grain growth, static recrystallization and phase transformation phenomena occurring at the microstructure level. Obtained results of simulations as well as performance characteristics are also presented in the paper. As a result, the CA framework, which supports design of complex algorithms with flexible data flow and reusable components is proposed.

System for flexible modelling of production cycles based on flat rolling

Rauch L., Madej L., Golab R., Pietrzyk M.

Journal of Machine Engineering

2009

Vol. 9, No. 4

39--48

The paper presents design and implementation of computer system dedicated to simulation of production cycles based on the rolling processes. The main functionality of the computer system, i.e. support and facilitation of flat rolling technology design, is obtained through flexible interface combined with the modular architecture of numerical library and optimization procedures. Each production cycle (e.g. heating, rolling, cooling, coiling) is prepared to be calculated separately and finally integrated into the sophisticated production cycle. The architecture of designed software as well as models used for numerical calculations are described in details.The system was tested for various configurations of rolling mills. Three of them together with obtained results are presented in the paper: complex production cycle (roughing and finishing rolling), finishing rolling composed of seven passes and laboratory case study.
