Silva, J.E., Garbatov, Y. and Guedes Soares, C. (2011), “Ultimate strength assessment of ageing steel plates subjected to random non-uniform corrosion wastage”, Advances in Marine Structures, C. Guedes Soares and W. Fricke, (Eds.), Taylor & Francis Group, London, UK, pp. 213-220

The aim of this study is to investigate the effect of non-linear randomly distributed nonuniform corrosion on the ultimate strength of unstiffened rectangular plate subjected to axial compressive loading. A series of 570 plate surface geometries are generated by Monte Carlo simulation for different degree of corrosion, location and ages and nonlinear finite element analyses are carried out, using a commercial finite element code. Based on a regression analysis, empirical formulae to predict strength reduction because of corrosion have been derived demonstrating a good accuracy.
