【Abstract】 The magneto-elastic effects in a thin current carrying conical shells under the combined action of electro-magnetic field and mechanical load are studied based on the nonlinear magneto-elastic kinetic equations of revolutionary shells. Through specific examples,the relationships between the electric current density and the displacement and the stress in a thin current carrying conical shells are obtained. The singularity in the apex of the conical shell is solved, and the numerical solution in an axisymmetric problem is obtained too. The computed results show that the stress and deformation in the thin current carrying conical shells can be controlled by changing the electric current density.更多还原
