Abstract

We study the inflation of weakly magnetizable isotropic membranes in the presence of externally applied magnetic field. The relevant governing equations, boundary conditions, and stability criteria are derived from a variational formulation and computational solutions are obtained for three geometries – circular, cylindrical, and toroidal membranes. It is observed that magnetic field can alter the onset of elastic limit point instability and introduce new magnetic limit points. Multiple stable equilibrium configurations are predicted for a given coupled load. We also observe induction of wrinkling in the membrane due to the magnetic field.
