Increasing effort has been made into understanding this so called mechano-electrochemical phenomenon through theoretical, experimental and numerical studies. However, current practice of marine structural analysis often adopts empirically based corrosion models. The majority of these models are derived from historical data and do not explicitly reflect the influence of the actual service conditions such as the mechanical loading. As a result, it is difficult to incorporate realistic corrosion features, often localised and non-uniform, in structural models. This study implemented in situ corrosion experiments into structural strength assessment to incorporate the corrosion-stress interactions over time. This enables the model to capture the dynamic change in thickness reduction spatially and temporally. Bench-shaped features are obtained, closely resembling the corrosion patterns observed in reality. A failure mode change is observed compared to models with uniform thickness reduction.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Corrosion patterns,Electrochemical phenomena,Experimental and numerical studies,Mechanical loading,Service conditions,Stress interaction,Structural strength,Thickness reduction[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to thank Lloyd’s Register Foundation and Indonesian Endowment Fund for Education (LPDP) for the sponsorship of this research.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1201/9780429298875-48[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
