This invention discloses a simulation method for laminated thin-walled structures based on higher-order plate elements, belonging to the field of computational structural mechanics. The method first constructs a novel higher-order plate theoretical model, which employs a displacement field within a single mathematical sublayer plate, characterized by cubic changes in in-plane displacement along the thickness and quadratic changes in lateral displacement. It innovatively introduces the physical displacements of the top and bottom surfaces of the sublayer plate as independent unknowns, which, along with the mid-surface displacement, describe the deformation. Based on this, a "sublayering" strategy is used to model the laminated thin-walled structure by flexibly dividing it into several sublayer plates in the thickness direction. Adjacent sublayer plates are directly connected by sharing unknown surface displacements, achieving efficient and high-fidelity modeling of the laminated thin-walled structure. The method further introduces physical layering by separating common nodes between adjacent sublayer plates and automatically handles the layered closure state using a penalty function method. Finally, the macroscopic response and local detailed stresses of the structure can be efficiently obtained through finite element method.
