利用集成压电层对温度梯度作用下的功能梯度材料(FGM)壳体进行了静、动态控制。基于假定的自然应变和改进的假定应变法，建立了一种EAS压电实壳元。详细分析了组成体积分数和反馈控制增益对功能梯度材料壳体系统静、动态响应的影响。
An attempt on the static and dynamic control of functionally graded material (FGM) shells subjected to temperature gradient is carried out by using integrated piezoelectric sensor/actuator layers. Based on the assumed natural strain and enhanced assumed strain method, an EAS piezoelectric solid shell element is developed. The effects of constituent volume fraction and feedback control gain on the static and dynamic responses of the FGM shell system are demonstrated in detail.
