  • Abstract
    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.
