微磁无损评估和测试技术对于评估钢部件的塑性应变特别有效。一种源自磁增量磁导率实验装置、称为涡流磁特征 (EC-MS) 的新方法似乎特别适合此类评估。 EC-MS 的数值模拟以前从未进行过。本文首先描述了 EC-MS 方法，然后提出了一种基于改进的 Jiles-Atherton 模型并扩展到动态行为的块标量唯象模型，用于其模拟。所有模拟细节均通过物理观察进行揭示和验证。微磁无损评估和测试技术对于评估钢部件的塑性应变特别有效。一种源自磁增量磁导率实验装置、称为涡流磁特征 (EC-MS) 的新方法似乎特别适合此类评估。 EC-MS 的数值模拟以前从未进行过。本文首先描述了 EC-MS 方法，然后提出了一种基于改进的 Jiles-Atherton 模型并扩展到动态行为的块标量唯象模型，用于其模拟。所有模拟细节都通过物理观察公开并证明是合理的。
Micro-magnetic nondestructive evaluation and testing techniques are particularly efficient for the evaluation of plastic strain in steel components. A new method derived from the magnetic incremental permeability experimental setup and called Eddy Current Magnetic Signature (EC-MS) seems to be the particularly adapted for such evaluation. Numerical simulation of EC-MS has never been done before. In this article, the EC-MS method is described first, then a lump scalar phenomenological model based on a modified Jiles-Atherton model and extended to dynamic behavior is proposed for its simulation. All the simulation details are exposed and justified with physical observations.Micro-magnetic nondestructive evaluation and testing techniques are particularly efficient for the evaluation of plastic strain in steel components.
