portion of the model was developed by assuming that each segment of the beam
could be represented as a simple second-order system. Future efforts to model beam
motion more accurately by modifying the method used to model the forcing moment,
by expanding the model to predict the performance of beams of all dimensions, and
by validating model performance against actual beam motion were recommended

This section presents a summary of the effort to model the deflection dynamics of
iono-elastic beams made of IPMNCs. Strips of these composites can undergo large
bending and flapping displacement if an electric field is imposed across their thick-
ness. IPMNC beams show large deformation in the presence of low applied voltage
