Symplectic superposition method-based new analytic bending solutions of cylindrical shell panels
TL;DR: In this paper, the authors extended the up-to-date symplectic superposition method to bending of cylindrical panels, with focus on clamped panels and their variants, by introducing the problems into the Hamiltonian system (in physics) and the symplectic space (in mathematics).

New analytic buckling solutions of side-cracked rectangular thin plates by the symplectic superposition method
TL;DR: In this article, a side-cracked rectangular thin plate is decomposed into several sub-plates that are analytically solved by the superposition method, where the symplectic eigenvalue problems are formulated, followed by the manifold expansion.

On new buckling solutions of moderately thick rectangular plates by the symplectic superposition method within the Hamiltonian-system framework
TL;DR: In this paper, the authors explore the symplectic superposition method for analytic buckling solutions of non-Levy-type moderately thick rectangular plates, which were hard to tackle by classical semi-inverse methods.
27
New benchmark free vibration solutions of non-Lévy-type thick rectangular plates based on third-order shear deformation theory
TL;DR: In this paper, a novel symplectic superposition method was proposed for thin/moderately thick plate problems, which was extended to free vibration problems of thick rectangular plates based on the TSDT.

New analytic bending, buckling, and free vibration solutions of rectangular nanoplates by the symplectic superposition method.
TL;DR: In this paper, an analytic bending, buckling, and free vibration solutions of rectangular nanoplates with combinations of clamped and simply supported edges are obtained by an up-to-date symplectic superposition method.
