A FOUR-NODE RECTANGULAR ELEMENT FOR COMPOSITE SANDWICH PLATES WITH PIEZOELECTRIC ACTUATORS

  • 摘要: 依据Hoff型夹层板理论以及纤维增强型复合材料和压电致动器的本构关系,首次建立了每个结点具有7个位移自由度的含压电致动器的四结点矩形复合材料夹层板单元.数值算例表明,方法具有良好的计算精度.

     

    Abstract: Based on the theory of the Hoff type sandwich plates, the finite element formulation of sandwich plates with piezoelectric actuators is established. The constitutive relationships of fiber-reinforced composite materials and piezoelectric actuators are employed in the formulation. A four-node rectangular sandwich plate element with seven degrees of freedom at each node has been established for the first time. Numerical example indicates that the element is effective and the result has high accuracy.
