Abstract
The paper presents a numerical simulation method for ship structures based on meshless local Petrov-Galerkin method. The proposal method is a suitable for adaptive computation method while processing the displacement and stress fields of the ship structures in high-gradient regions. Above all, based on the theory of Mindlin-Reissner plate, the field approximation function of the displacement is obtained by employing Moving-least Square method, and then the governing equation and the stiffness matrix of the structures are established. Numerical demonstrations show the solutions of the presented method are good agreement between FEM-ANSYS and the proposed approach, which verifies the validity of the presented method for the ship structures analysis.
