Abstract: In this work, we have proposed a general 3D analytical model for giant magnetostrictive composites based on the Mori-Tanaka theory. Taking into consideration both the interface effect and thermal residual stress (TRS) in the curing process, we have studied the relationship between the effective magnetostriction of giant magnetostrictive composites and different magnetic fields, and investigated the influence of TRS, inclusion shape, and direction of the magnetic field on the effective magnetostriction. The results show that TRS has significant influence on the effective magnetostrictive normal strains but little effect on the effective magnetostrictive shear strains. Both the magnetic field direction and the inclusion shape significantly affect the effective magnetostriction. Moreover, the Wiedemann effect is expected to occur on the giant magnetostrictive composites according to our theoretical calculations.
