Analysis of Stress Concentration Factors due to in-Plane Bending and out-of-Plane Bending Loads on Tubular TY-Joints of Offshore Structures

Abstract The aim of this work is to study the stress distributions and location hot spots in vicinity intersection lines tubular elements TY-joints. Using finite element models, we analyze effects geometrical parameters on concentration factor case in-plane bending out-of-plane loads, around weld toe joints. Our results reveal maximum at heel or loads saddle point loads. Six parametric equations are established used calculate critical locations using non-linear regression method. obtained from analysis close experimental data previous work.
