Abstract | [Abstract]: A stabilized conforming nodal integration (SCNI) method is presented to formulate two efficient smoothing piezoelectric elements for static analysis of planar piezoelectric structures with quadrilateral mesh. The approximations of mechanical strains and electric potential fields are normalized by the smoothing constant function of the SCNI technique over each smoothing cell. This method allows field gradients to be directly computed from interpolating shape functions using boundary integrations along each edge of the smoothing element. The boundary integration will contribute to the preservation of high accuracy of the method even when elements are extremely distorted, for example, a concave quadrilateral. No mapping or coordinate transformation and derivatives of shape functions are necessary so that the original meshes with badly shaped elements can be used. The present elements do not introduce any additional degrees of freedom and are easy to implement into an existing finite element method (FEM). Numerical examples and comparative studies with analytic solutions are presented to demonstrate the simplicity, efficiency and accuracy of the elements. |
