| Abstract: | This paper analyzes the deformations in unbalanced piezoelectric composites under the same loads and driving voltages using the 4-node rectangular piezoelectric laminated plate finite element, which is based on the first-order shearing deformation theory. The deformation states are calculated for five kinds of unbalanced laminated piezoelectric plates with different ply conditions. At the same time, the effect laws, how the bending-twisting coupling coefficients affect the deformation of unbalanced piezoelectric composites, are also researched basically. The results are meaningful for the future design . |
