层压电工钢的磁性能在冲孔过程中下降，因为沿切削刃的塑性局部化，但也因为残余应力，这可能会蔓延到整个层压。本文通过简化力学分析，分析了长程残余应力。然后，利用磁弹性耦合模型计算了它们对层合材料整体磁性行为的影响。研究发现，残余应力的相对影响与塑性的相对影响同样重要。
The magnetic properties of laminated electrical steels are degraded by punching because of plasticity localized along the cutting edge, but also because of residual stresses, which may spread over the whole lamination. In this article, long-range residual stresses are analyzed via a simplified mechanical analysis. Then, their effect on the global magnetic behavior of the lamination is calculated by a magnetoelastic coupled model. It is found that the relative influence of residual stress is as important as the one of plasticity alone.
