| الوصف: | Fatigue failure is a grave technical issue in welded structures; it is caused by the stress concentration at the discontinuity of the weld toe or root. Therefore, many research studies have been performed to establish appropriate S–N curves for welded joints via fatigue tests and Finite element analysis (FEA). In almost all fatigue tests, it has been found that the loading point is far from the points of concern where fatigue life is investigated, and the fatigue life of the welded joint is not affected by the stress singularity at the loading points. However, when the loading point is close to the welded joint, the peak stress at the welded joint is affected by both geometry discontinuity at the welded joint and uneven stress distribution at the loading point. This paper presents the validity of S–N curves for welded structures with a concentrated load close to the welded joint. The stress behaviors of structures with a concentrated load are defined via stress measurements and FEA. Fatigue evaluations are performed via fatigue tests and corresponding FEA. |
