在这项工作中，元胞自动机（CA）模型是第一次开发，以预测材料的微观结构演变过程中的切削过程。在CA模拟之前，通过基于有限元的切削模型模拟了由各种正交切削条件引起的工件材料铝合金1100的动态热机械载荷。位错密度的演变模拟使用CA模型在MATLAB中的工作材料进行这些负载条件。CA模型中耦合了多种微观组织演化机制，包括剧烈塑性变形、动态回复、动态再结晶和热驱动晶粒长大。
In this work, a Cellular Automaton (CA) model is for the first time developed to predict material microstructure evolution during cutting processes. Prior to the CA simulation, the dynamic thermomechanical loadings of work material, Aluminum Alloy 1100, induced by various orthogonal cutting conditions are simulated by finite element-based cutting models. Evolution of dislocation density is modeled using the CA model in MATLAB for the work material subjected to these loading conditions. Multiple mechanisms of microstructure evolution are coupled in the CA model including severe plastic deformation, dynamic recovery, dynamic recrystallization, and thermally-driven grain growth.
