Abstract:
In assessing fatigue life of welded components a reliable determination of fluctuating stress is required. The stress distribution in welded joints primarily depends on geometry, stress concentration, loading case and material elastic or plastic behavior. Classical analysis of fillet weld joints is not generally feasible when complex geometry and load cases are involved. The Finite Element Modeling, when properly integrated with the weld parameters can be of great help for calculating these stresses. In this paper a T-joint FE model was used to investigate the best modeling approach to this type of joint when subjected to combined load cases. Finally, a fatigue life estimation, using the Stress × Life (S × N) approach from British Standard BS-7608 is then performed.
