Garbatov, Y., Tekgoz, M. e Guedes Soares, C. (2011), “Uncertainty assessment of the ultimate strength of a stiffened panel”, Advances in Marine Structures, C. Guedes Soares and W. Fricke, (Eds.), Taylor & Francis Group, London, UK, pp. 659-668
The objective of this work is to analyze various uncertainties related with the prediction of the ultimate strength of a stiffened panel. The effect of different structural parameters on the uncertainty is evaluated based on Monte Carlo simulation and an ANOVA methodology is used to determine the most relevant parameters. The ultimate strength is predicted by the finite element method and the influence of plate thickness, Young modulus, yield and ultimate tensile strain of material, the shape of the initial geometry imperfection and slenderness ratios are accounted for.
