中文摘要：

在这篇论文，磁性的有弹性的塑料变丑行为与简单支持为一个铁磁性的盘子被学习。磁性的力量的不安公式首先基于不安技术被导出，并且然后被用于变丑特征的分析，强调在模式的分析上放了，变丑的对称和板变丑上的应用磁场的事件角度的影响。有在一个倾斜的磁场下面的简单支持的铁磁性的矩形的板的配置是在里面起浪的理论分析提议解释沿着 x 方向打字，并且铁磁性的板的最大的变丑为什么为磁场发生在 45 °的事件角度。数字代码基于有限元素方法被开发模仿份量上行为线性地非联合了多地问题。一些典型曲线被阴谋说明磁电机橡皮塑料偏转，并且揭示偏转怎么能被应用磁场的事件角度影响。从数字模拟获得的变丑特征在对理论分析的好同意被发现。

英文摘要：

In this paper, the magnetic-elastic-plastic deformation behavior is studied for a ferromagnetic plate with simple supports. The perturbation formula of magnetic force is first derived based on the perturbation technique, and is then applied to the analysis of deformation characteristics with emphasis laid on the analyses of modes, symmetry of deformation and influences of incident angle of applied magnetic field on the plate deformation. The theoretical analyses offer explanations why the configuration offer- romagnetic rectangular plate with simple supports under an oblique magnetic field is in-wavy type along the x-direction, and why the largest deformation of the ferromagnetic plate occurs at the incident angle of 45°for the magnetic field. A numerical code based on the finite element method is developed to simulate quantitatively behaviors of the nonlinearly coupled multi-field problem. Some characteristic curves are plotted to illustrate the magneto--elastic-plastic deflections, and to reveal how the deflections can be influenced by the incident angle of applied magnetic field. The deformation characteristics obtained from the numerical simulations are found in good agreement with the theoretical analyses.
