An elastic disk is coated with an elastic rod, uniformly prestressed with a tensile or compressive axial force. The prestress state is assumed to be induced by three different models of external radial load or by ‘shrink-fit’ forcing the coating onto the disk. The prestressed coating/disk system, when loaded with an additional and arbitrary external load, experiences displacement, strain, and stress

In the finite magnetoelastic deformation context, the Zeeman magnetic energy on its own is found to be inconsistent with the general theory of nonlinear magnetoelasticity. An appropriate additional term, depending on the definition of the reference configuration magnetization, is used to modify the total magnetoelastic energy to confer consistency. In particular, this confirms that the total Cauchy
