Analyses of the magneto-elastic-plastic behavior of a nonlinear ferromagnetic beam-plate with unmoved simple supports

摘要

Based on the general expression of magnetic force from the variational principle of ferromagnetic plates, a numerical code is established in this paper to quantitatively analyze the behavior of magneto-elastic-plastic interaction of ferromagnetic beam-plates with un-movably simple supports. Along with that the phenomena of buckling, bending and post-buckling/snapping or the characteristic curves of deflection versus magnitude of applied magnetic fields are displayed, the critical magnetic values of buckling/snapping after the plates undergo plastic deformation, and the evolvement of deflection configuration of the plate are numerically obtained in a case study.
