Stress Concentration Factor Evaluation of Offshore Tubular KT Joints Based on Analytical and Numerical Solutions: Comparative Study

Fatigue damage is treacherous and can lead to the failure of offshore structures. The purpose of this research is to evaluate and discuss the stress concentration factor (SCF) values for two geometries of offshore tubular KT joints using different calculation methods to be used in fatigue design. The work was done by using analytical calculations, formulations from the literature, and numerical solutions, finite-element method (FEM) analysis...
