A new finite element based upon an elastic equivalent single-layer model for shear deformable andstraight magneto-electro-elastic generally laminated beam is presented. The element has six degreesof freedom represented by the displacement components and the cross-section rotation of its two nodes.The magneto-electric boundary conditions enter the discrete problem as work-equivalent forces andmoments while the electro-magnetic state characterization constitutes a post-processing step. The elementpossesses the superconvergence property for the static problem of beams with uniform crosssectionand homogenous material properties along the beam axis direction. Moreover, it is free fromthe shear locking phenomenon. The developed finite element is validated through comparison withplane-stress results for piezoelectric and magneto-electro-elastic structures. Last, applications for morecomplex magneto-electro-elastic systems are described.
