Abstract: A piece-wise Ritz method to obtain a precise and valid solution used to analyze laminated shell structure is developed. In this method, the laminated shell structure is divided into patches and represented by parametric surfaces that are connected in boundary according to C0 continuity. The trial functions of Ritz procedure with parametric surface characteristics are constructed to get functional and governing equations. Finally, an illustrative example is given an d the results show the correction and validity of present piece-wise Ritz method.
Keywords: Laminated shell, parametric surface, piece-wise Ritz method.
