Development of Shell Element to Analyze an Intelligent Structure with Piezoelectric Sensor／Actuator

압전 감지기／작동기를 포함하는 쉘 요소의 개발

A new three-dimensional thin shell element for the structure containing an integrated distributed piezoelectric sensor and actuator is proposed. A finite element formulation for the static response of the shell with piezoelectric sensor／actuator is derived. The assumed strain formulation and the bubble function improves the performance of the shell element. The verification through the calculation of the static response for the piezoelectic bimorph beam shows that the results agree with those from the theoretical analysis very well.
