Huang, W., Garbatov, Y. e Guedes Soares, C. (2012), “Fatigue damage assessment of stiffener-frame structure”, Maritime Engineering and Technology, Guedes Soares et al. (Eds),Taylor & Francis Group, London, pp. 301-307
This paper presents a fatigue damage analysis of very complex stiffener frame ship structures. A three-dimensional finite element model is generated and linear elastic finite element analysis is performed. Hot-spot stresses of a stiffener-frame structure are analyzed applying 20-node solid elements using a commercial finite element code. Based on a FEM analysis, hot-spot stresses are determined and fatigue damage is quantified employing the S-N approach. Comparative analysis of fatigue damage for all hot spots is presented and the difference between numerical predictions is discussed.
