Finite element method for multiple laminated structures and its applications.

In this paper, the numerical analyzing method for multiple laminated structures, which are composed of some plates and some layers bonding them, is proposed. The finite element method is applied in the technique by using the special connective element for the adhesion part and the normal two-dimensional element for the plate part. As numerical examples, two-and three-laminar-structure models are analyzed. The results coincide with the values evaluated using the three-dimensional finite element method (3DFEM). Moreover, the calculation time and the memory capacity of the computer are largely decreased compared with the case of 3DFEK.
