STUDY OF FINITE ELEMENT ANALYSIS AND SHAPE CONTROL OF COMPOSITE LAMINATE CONTAINING PIEZOELECTRIC ACTUATORS/SENSORS

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 minimumt ot alpotential energy. And an FEA code was also implemented and verified to the static analysis of composite laminate containing peizoelect ricactuators/sensors. Fur thermore, shape control was investigated for such composite plates.
