| Abstract: | The theory of composite laminate with distributed actuators and sensors was studied. Based on the study, a four node composite plate element with displacement and electrical degrees of freedom was developed. Then the static equilibrium equations were derived by using the principle of minimum total potential energy. And an FEA code was also implemented and verified to the static analysis of composite laminate containing peizoelectric actuators/sensors. Furthermore, shape control was investigated for such composite plates. |
