| Abstract: | Nonlinear FEM was performed for the ultimate strength analysis for series ship girders with cutout subjected to longitudinal compression.Base on the numerical results,a prediction formula for the ultimate strength assessment of ship girders was presented.Comparisons between nonlinear FEM results and the ones of the proposed formula showed that the proposed prediction formula is reasonable with high accuracy. |
