%X The magnetoelectric (ME) effect is a product property of the composite material consisting of individual piezoelectric and magnetostrictive phases. Based on the constitutive equations of the materials, the ME coupling of a symmetrical magnetostrictive/piezoelectric laminated composite is modeled using a simple static elastic method. The ME coupling is also simulated by numerical technique employing the ANSYS 8 0/Multiphysics finite element software. It is found that the ME voltage coefficient in the static method is quite close to that in the equivalent circuit approach and increases with the increase of the magnetostricive/piezoelectric thickness ratio. Using the numerical modeling we can calculate the ME voltage coefficient of the magnetostrictive/piezoelectric laminated composite effectively.
