000015333 520__ $$2eng$$aTo simulate multi-physics phenomena that occur in multi-functional devices such as load bearing antennae and piezoelectric induced damage detectors, a model is developed to couple transient electromagnetic (EM) and dynamic mechanical fields in a finite deformation setting with damage evolution features. To achieve a versatile coupling scheme between fields, the problems are solved in a staggered way using a time-domain finite element (FE) method by a high performance parallel program. A constitutive model of a piezoelectric material is implemented with a phenomenological damage model to simulate piezoelectric damage sensors undergoing dynamic finite deformation. Moreover, A multi-time scaling method is implemented to overcome the computational infeasibility posed by analyzing the rapidly varying EM quantities while accounting for the effects of the slow evolution of the mechanical displacement field in deformable antenna applications.
