Abstract Based on the Mori-Tanaka theory, we considered the influence of interface effect on giant magnetostriction composites, and obtained the general analytical expression of giant magnetostriction composites effective properties. The thermal residual stress in the curing process has an impact on the effective properties of giant magnetostriction composites which is also considered. Through numerical calculation, the results show the changes of the effective modulus, the effective magnetostriction, the effective thermal expansion coefficient of high magnetostriction composites with inclusion’s aspect ratio, inclusion’s volume fraction and interfacial parameters. Interface and thermal residual stress significantly affected effective properties of giant magnetostriction composites.
