✦ Synopsis

Two kinds of the ®nite layer method, i.e. semi-analytical ®nite layer method and spline ®nite layer method, are developed in threedimensional analysis of rectangular composite laminates with actuator and sensor layers (piezoelectric materials). The generalized displacement functions are constructed, and the generalized stiness matrices are derived in explicit form, which are especially convenient for application in engineering. Numerical examples are presented and compared with available results to demonstrate the eciency and accuracy of the present method. The ®nite strip formulation for two-dimensional problems of piezoelectric laminates and the ®nite layer formulation for three-dimensional analysis of orthotropic and isotropic elastic laminates are the degenerated cases of the present formulation.
