Buckling of three layer rectangular polyethylene plate with ferrofluid under magnetic field
Abstract eng: The paper is devoted to the buckling of a rectangular plate made of polyethylene. The plate consists of three layers: two external faces and a porous core. On the two opposite edges, there are pockets filled with ferrofluid. The pockets have a porous structure to avoid ferrofluid flow along the edge. Each pocket is placed in a magnetic field generated by a system of magnetic field coils. The coil system is built of two subsystems: a main coil and a gradient coil. The main coil is a Helmholtz coil with high homogeneity of magnetic field. The gradient coil is a “saddle” coil with high homogeneity of transverse gradient magnetic field. Such systems of coils generate a magnetic field that changes in space. The generated magnetic field acts on the ferrofluid in the pockets on the edges of the plate, and induces a compression force there. Critical states are described for static load, and dynamic equilibrium paths are obtained for an example plate.
