Multifunctional Composite Materials (MCMs) are an enabling smart structures technology. Their properties can be tailored to meet specific engineering requirements due to a combination of unique features, often possessing functionalities such as actuation, sensing, and energy harvesting material. An approach is presented in which closed form solutions are used to gain insight into field concentrating effects within simple geometries. These solutions are used to validate multiphysics models, followed by the introduction of more complex geometries used to evaluate material behavior within representative volume elements. This modeling approach is used to design experiments to evaluate self-assembly using dielectrophoresis, and the ability to polarize the ferroelectric phase in a ferroelectric particle - polymer matrix composite.
