Paper Abstract

A variational model of the nonlinear response of a magnetostrictive actuator to applied magnetic fields and loads, taking into account the complex behavior of the underlying domain patterns, is discussed. Magnetostriction curves for a Terfenol-D-like material in a 2D geometry are calculated exactly, and compared with experimental measurements for Terfenol- D, suggesting an explanation for the observed behavior.
