悬臂铁磁板磁弹性耦合作用的力学分析

MECHANICAL ANALYSIS OF MAGNETOELASTIC COUPLING INTERACTION TO CANTILEVERED FERROMAGNETIC PLATES WITH FINITE WIDTH

对有限板宽的悬臂铁磁板在外磁场中的磁弹性相互耦合作用的力学行为，建立了描述板弯曲和稳定性的理论模型及有限元定量分析程序。

In order to simulate the mechanical behavior of magnetoelastic coupling interaction for the ferromagnetic cantilevered plates with finite width when they are placed in an applied magnetic field. A FEM analysis program is proposed to characterize the phenomena of magnetoelastic bending and instability of the plates. After that, we study the effect of incident angle of obliquely applied magnetic fields on the critical magnetic fields of magnetoelastic instability.
