Hypernormal Form at Quintic of the Rectangular Symmetric Cross-ply Composite Laminated Plates

Jiao Wang, Jing Li, Bin He


In this paper, we applied the method of new grading function which is combined with multiple Lie brackets to investigate the hypernormal form of the rectangular symmetric cross-ply composite laminated plates. With the aid of Maple and new expressions of block matrices, we obtained the hypernormal form at quintic truncated and proved that it was an unique one under certain conditions.
