• We analyze the buckling of soft ferromagnetic FG circular plates made of poro material.
• Modulus of elasticity of porous plate is as a power law through the thickness.
• The porous plate is assumed of the form that pores are saturated with fluid.
• Increasing the porosity decreases the critical buckling load.
• Equilibrium and stability equations of a poro circular plate in transverse magnetic field are derived.
This study presents the buckling analysis of soft ferromagnetic FG circular plates made of poro material. Equilibrium and stability equations of a poro circular plate in transverse magnetic field are derived. This study analyzes the poroelastic instability of clamped edge ferromagnetic plates subjected to magnetic loadings. The geometrical nonlinearities are considered in the Love–Kirchhoff hypothesis sense. In this paper the effect of pore pressure on critical magnetic field of plate and the effect of important parameters of poroelastic material on buckling capacity are investigated. Also the compressibility of fluid and porosity on the buckling strength are being investigated.
