这项研究的重点是对局部腐蚀的钢板和加筋板进行比较。有限元分析用于研究随机腐蚀对海洋结构单元抗压强度的影响。变量包括腐蚀程度；长细比和长径比。结合腐蚀预测模型来确定厚度随时间的减少。与加筋板相比，腐蚀引起的体积损失会导致细长板的极限强度更大程度地降低，高达 45%，这表明结构元件的选择可以强烈影响估计腐蚀损伤效应的准确性。
This study concentrates on a comparison between steel plate and stiffened panels subject to localised corrosion. A finite element analysis is used to investigate the effect of random corrosion on the compressive strength capacity of marine structural units. Variables include the extent of corrosion; slenderness ratio and aspect ratio. A corrosion prediction model is incorporated to determine the thickness reduction with time. Corrosion-induced volume loss results in a greater reduction of ultimate strength for slender plates compared to stiffened panels, up to 45%, showing the structural element selection can strongly influence the accuracy of the estimated corrosion damage effect.
