| Abstract: | According to the theory of elasticity and piezoelectricity and the theory of three-dimensional finite element analysis,the global stiffness matrix of piezoelectric laminates is deduced by using the 3-D isoparametric element. And based on physical and geometrical characteristics of the material, the stresses and deformations of the piezoelectric laminates are calculated. A simply supported rectangular plate is analyzed as a numerical example and the results are compared with the existing analytic solutions. The calculations illustrate that the present results have high precision. |
