Fatigue design of plated structures using finite element analysis

Abstract

Finite element analysis is being used by designers for fatigue assessment of structures. It is therefore important that a proper link between calculated hot spot stress and fatigue capacity is established, and that guidance on such analysis is included in design standards. This paper presents a summary of the finite element analyses performed for assessment of hot spot stress with link to one hot spot S–N curve in the FPSO Fatigue Capacity Joint Industry Project. Recommendations are presented on how to perform fatigue assessment of plated structures based on finite element analysis combined with one hot spot S–N curve. © 2006 Taylor & Francis Group, LLC.
