Paper Abstract

This paper presents a quasi-static variational principle and finite element scheme to model the nonlinear interactions between mechanical and magnetic fields in magnetostrictive materials. The basis of the above finite element scheme is presented here and applied to simulation of the direct and converse response of a magnetostrictive rod. While the nonlinear scheme developed is of general three dimensional nature, the application examples utilize material property data that pertain to the crystalline and geometrical symmetry of commercially produced Terfenol-D. The role of nonlinear magnetic body forces and nonlinear constitutive properties is examined in detail.
