Abstract

Structural steel corrosion is a critical engineering problem that can lead to catastrophic failures, resulting in loss of life, environmental harm, and substantial economic damage. Notable incidents, such as offshore platform collapses and ship hull breaches, have demonstrated the severe consequences of undetected or underestimated corrosion. In marine environments, crevice corrosion presents a particularly challenging case, as confined chemical conditions and the presence of barnacles promote localized degradation. Barnacles generate microcracks that accelerate the deterioration process. However, finite element modeling of crevice corrosion remains scarce and often relies on oversimplified geometries, which limits the accuracy in capturing actual corrosion volume, depth, and affected area. This study develops a 3D finite element model of barnacle-induced crevice corrosion on 316L stainless steel plates, based on long-term immersion data. Corrosion geometries were analyzed using laser scanning microscopy, with the analytical mapped field feature applied under transverse loading and random pit positions for exposure durations of 6, 12, and 36 months. The results reveal progressive increases in displacement (up to 17.27%), strain (30.8%), and stress (20.12%) compared to uncorroded plates, underscoring the substantial impact of localized corrosion on structural performance.
