本文研究铁磁多尺度材料的建模问题。我们提出了一个计算均匀化技术的基础上的非均匀多尺度方法（HMM），包括涡流和迟滞损失在中尺度。HMM包括：1）宏观尺度问题，捕捉整体解的缓慢变化; 2）许多中尺度问题，允许确定宏观尺度的本构律。作为应用实例，考虑了叠层铁芯。
In this paper, we investigate the modeling of ferromagnetic multiscale materials. We propose a computational homogenization technique based on the heterogeneous multiscale method (HMM) that includes both eddy-current and hysteretic losses at the mesoscale. The HMM comprises: 1) a macroscale problem that captures the slow variations of the overall solution; 2) many mesoscale problems that allow to determine the constitutive law at the macroscale. As application example, a laminated iron core is considered.
