Bending and buckling of ferroelastic plates

A theoretical study of bending and buckling of ferroelastic plates in the p resence of magnetic fields is carried out based on the model that takes int o account the nonlinear field-structure interaction. The resultant force sy stem derived from the interaction between magnetic fields and ferromagnetic materials is composed of the body force only. Using this model, the bendin g and buckling problems of a cantilevered ferromagnetic plate and simply su pported rectangular plates in transverse and oblique magnetic fields are in vestigated with the aid of a numerical approach. Numerical results reveal s ome interesting features of magnetoelastic bending and buckling phenomena d ue to the nonlinear nature of the field-structure interaction.
