Numerical Simulation of Magnetoelastic Buckling to Ferro-magnetic Cantilevered Plate in Transverse Magnetic Field1
Based on magnetostrictive material model which neglects the effect of volume expansion and contraction, the basic equation for magnetoelastic analysis is derived in this paper. The theory is easy to understand and easy to derive, and it is numerically simulated using FEMLAB that the magnetoelastic buckling of cantilevered ferromagnetic plate in transverse magnetic field. The critical magnetic induced intensity of the simulation agrees with that of former experiments. The numerical simulation shows that the critical magnetic induced intensity decreases when the ratio of the length and thickness of the plate or the magnetic strain coefficient increases. When the magnetic strain coefficient ω=1.4×10-5T-1 is used, the results of the simulation accord with that of the experiment is best . The numerical analysis shows that it is reasonable to use magnetostrictive material model to analyze the magnetoelastic buckling of ferromagnetic cantilevered plate in transverse magnetic field.
