In this study, three types of multi-layered and higher-order-deformable (ML/HOD) plate/shell finite elements, I.e. [(110)(110)(110)], [(110)(332)(110)] and [(332)(332)(332)], in which the order of displacement assumptions are selectively considered layer by layer in a flexible and versatile manner, were developed for accurate numerical analysis of structural sandwich and composite laminates. The developed sandwich finite elements were then applied to the structural numerical analysis of a square sandwich plate under uniform pressure. The numerical results obtained by the developed finite elements indicated that all of the three models were more accurate than the conventional ESL-based models such CLT, FOSDT. In addition, since the numerical accuracy of [(110)(110)(110)] model was slightly inferior to the other two models, I.e. [(110)(332)(110)] and [(332)(332)(332)] and also from the view point of computational efficiency, the optimum numerical model turned out to be [(110)(332)(110)] among the three models.
