Stress concentrations in simple tubular joints

all geometrical influences except the local weld notch effect. If we examine the stresses close to the weld we can see that they increase rather smoothly in areas that are not too close to the weld. This increase is due to the geometric influence of the joint. Very closely to the weld we find a rapid increase in stresses due to the weld geometry.Review of Fatigue Assessment Methods for Welded Steel structural notch effect in steel welded jointsDue to high stress concentrations, welded joints represent the most common locations of fatigue crack initiation in steel structures that are prone to fatigue.

Investigation on the effect of geometric and structural structural notch effect in steel welded joints

Aug 01, 2017 · The paper presents an analysis of complex fatigue notch in welded joints, defined through the effect of both geometric notch and structural notch. The undertaken analysis involved fatigue tests conducted using S355N steel test pieces without a notch and with geometric, structural and complex notch. The test results were used to compare fatigue lives of notchless elements with fatigue lives of elements with each notch IIW Recommendations for the Fatigue Assessment by Notch structural notch effect in steel welded jointsThe notch stress approach for fatigue assessment of welded joints is based on the highest elastic stress at the weld toe or root. In order to avoid arbitrary or infinite stress results, a rounded shape with a reference radius instead of the actual sharp toe or root is usually assumed.
