A variational modeling of magneto-thermo-elasticity for nonlinear ferromagnetic plates

摘要：

The mechanical behaviors of ferromagnetic plates immersed in applied magnetic and thermal fields are addressed in the present paper. The generalized variational principle of magnetoelasticity is expanded to the magneto-thermo-elastic interaction of a soft ferromagnetic plate with dual nonlinearities of magnetization and geometrical large-deflection under thermal and magnetic fields. As an application of the variational model suggested, we analytically analyze the magneto-thermo-elastic buckling of a ferromagnetic simply supported rectangular plate under both a uniform temperature field and a transverse magnetic field as an example. The critical values of magneto-elastic and thermo-elastic, as well as magneto-thermo-elastic buckling are obtained.
