Resumen

This paper provides examples of the numerical solution of boundary-value problems in nonlinear magnetoelasticityinvolving finite geometry based on the theoretical framework developed by Dorfmann andco-workers. Specifically, using a prototype constitutive model for isotropic magnetoelasticity, we considertwo two-dimensional problems for a block with rectangular cross-section and of infinite extentin the third direction. In the first problem the deformation induced in the block by the application of auniform magnetic field far from the block and normal to its larger faces without mechanical load is examined,while in the second problem the same magnetic field is applied in conjunction with a shearingdeformation produced by in-plane shear stresses on its larger faces. For each problem the distributionof the magnetic field throughout the block and the surrounding space is illustrated graphically, alongwith the corresponding deformation of the block. The rapidly in space changing magnitude of the magneticfield in the neighbourhood of the faces of the block is highlighted.Nota general
