| Abstract: | The structure stress in large deck opening is simulated by MSC-NASTRAN FEM program. The simple partial and whole models are established in order to calculate stress in large deck opening with different loading methods. Tolerances of the results calculated by different partial models are given by comparing with that of the whole structure. The scheme, whose calculative tolerance is smallest and modelling is the simplest, is presented. |
