The magnetoelectric effect, stemming from piezoelectric and magnetostrictive materials composite, is studied. A model based on the association of magnetoelastic and piezo-electric constitutive laws is presented. This model is implemented in a finite element formulation and a comparison with analytical solutions for piezoelectric/magnetostrictive composite is realized. A magnetoelectric displacement sensor is finally studied.
