The mechanical coupling effect in a magnetoelectric (ME) composite structure in which a magnetostrictive component is bonded with a piezoelectric one is simulated by numerical technique, focusing on an optimization of the magnetoelectric coupling output. The simulation starts from an experimentally developed ME composite structure and takes into account the mechanical coupling mechanism between the two components. A numerical optimization algorithm is developed, predicting a significant enhancement of the ME output by optimizing the component dimension. This algorithm can also be used for optimum design of other ME composite structures in terms of the largest ME output.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
