The paper employed the meshless local Petrov-Galerkin method to assess the ship structures stress analysis. The displacement field approximation function is obtained by employing Moving-least Square method,and the governing equation and the stiffness matrix of the structural are established. Numerical examples show the solutions are good agreement between FEM-ANSYS and the proposed approach, which verifies the validity of the presented method for stress analysis of the ship structural.
