A comprehensive analytical framework is developed for the study of magnetostrictive transducers with arbitrary geometries operated in dynamic regimes. Weak form equations are derived from Maxwell's equations and linear momentum without restricting the form of the constitutive behavior of the magnetostrictive material. For validation, the framework is implemented for a unimorph beam actuator which has both active and passive media.
