Abstract : This final report documents the results of the research and development activities focused on the development of a new generation of smart structures incorporating embedded hybrid multiple actuation systems which capitalize on the diverse strengths of both electrorheological fluids and piezoelectric materials, and employ fiber-optic sensing systems. A state-of-the- art review of smart materials and structures technologies has been undertaken, and an in-depth critique of the current generation of actuators and sensors for smart structures applications has also been presented. An in-depth review of analytical, computational and experimental investigations on controlling the vibrational characteristics of beams, plates and a variety of prototype structural systems has also been undertaken. Furthermore, variational formulations for predicting the performance characteristics of smart structures featuring hybrid embedded piezoelectric and electrorheological domains have been successfully developed. These formulations will form viable bases for the development of finite element design tools of Phase II.
