Stress Concentration Factors on Welded Tubular Joints
Fatigue is one of the most common failure modes of offshore structures. In the case of welded tubular joints, the assessment of hot spot stresses is considered to predict structure fatigue life during design phase, life extension studies and on inspection plan definitions. The estimation of welded joint hot spot stresses is based on stress concentration factors (SCFs), which are given by parametric formulae, finite element analysis or experimental tests. Depending on the structure geometry, these methods may furnish different results. Given their importance for the oil and gas industry, since they are the basis for the assessment of the fatigue life of welded tubular joints, the estimation of SCFs must be the most accurate as possible. Formulae to determine SCFs of welded tubular joints are available in the literature. The main purpose of this paper is to compare results obtained by a set of formulae adopted by the referred equations with finite element method results.
