Effect of Load Eccentricity on Stress Condition of Butt Welded Joint with Asymmetrical Reinforcement

Abstract

An analytical method for determination of a stress condition of butt welded thin-gauge plates with asymmetrical reinforcement is developed. The proposed method allows take into account the effect of the load application eccentricity on the tensile stress concentration factor (SCF) in the weld root zone. It is presented that the bending stresses, caused by this eccentricity, result in increasing the total stresses up to 75%. The results of analytical SCF calculations are in good agreement with the results obtained using the finite element method.

Effect of Misalignment of Axes in Double-Sided Weld on Stresses Distribution in Butt Welded Joints

“…An analytical method for SCF calculation [17] was developed based on the assumption that the axis of the root weld coincides with the axis of the face weld. But for real joints this is not always the case, and the axis of the root weld is offset by some eccentricity distance from the axis of the face weld (Fig.…”
