Study on magneto–elastic–plastic deformation characteristics of ferromagnetic rectangular plate with simple supports

摘要: In this paper, the magnetic–elastic–plastic deformation behavior is studied for a ferromagnetic plate with simple supports. The perturbation formula of magnetic force first derived based on technique, and then applied to analysis characteristics emphasis laid analyses modes, symmetry influences incident angle field deformation. theoretical offer explanations why configuration rectangular supports under an oblique in-wavy type along x-direction, largest occurs at 45° field. A numerical code finite element method developed simulate quantitatively behaviors nonlinearly coupled multi-field problem. Some characteristic curves are plotted illustrate magneto–elastic–plastic deflections, reveal how deflections can be influenced by obtained from simulations found in good agreement analyses.
