| Abstract: | A finite element formulation is presented for modeling the plate containing distributed piezoelectric sensors and actuators(S/As) An new plate bending element with electric degree of freedom for analysis the plate with distributed S/As is developed This element saves much memeroy and computational time On the basis of it a general method of static shape control for the intelligent structures is instructed Two examples are given to illustrate the application of the method presented in this paper |
