Abstract In this paper, the overall corrosion damage process is modelled sequentially using cellular automata (CA) to describe the localised corrosion component, and finite element analysis (FEA) to account for the mechanical component resulting from the stress concentration effect of the corrosion defect (pit). Synchronous execution of the CA and FEA, and provision of feedback between both provides a good approximation of stress-assisted pit development. Qualitative and quantitative comparison of simulation results with experimental measurements show good agreement. In particular, the model shows that mechanical effects, notably plastic strain, accelerates the rate of development of localised corrosion.

使用元胞自动机有限元方法模拟应力辅助局部腐蚀

摘要 在本文中，整个腐蚀损伤过程依次使用元胞自动机（CA）建模来描述局部腐蚀分量，并使用有限元分析（FEA）来解释腐蚀缺陷的应力集中效应引起的机械分量（坑）。CA 和 FEA 的同步执行以及两者之间的反馈提供了应力辅助坑开发的良好近似。模拟结果与实验测量的定性和定量比较显示出良好的一致性。特别是，该模型表明机械效应，特别是塑性应变，加速了局部腐蚀的发展速度。
