“…However, the proposed in [10] method does not take into account the bending stresses caused by the eccentricity of the tensile load application. These stresses cause changes in stress condition of the joint as follows: the face side total stress decreases and root side total stress increases [11]. This is confirmed by the tests of samples of 1460 Al-alloy butt joints, welded by TIG welding.…”

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.

“…On the second stage the nominal value of stress is to be multiplied by stress concentration factor (SCF) which can be calculated by an appropriate analytical method. For thin-gauge butt welded joints the values of reinforcement height and plate thickness are comparable [13]. This geometrical feature leads to the eccentricity of axial load and, consequently, to emergence of bending stresses which are put together with tensile ones on the root side [14].…”

An analytical method for calculation of local stresses in double-sided butt welded joints at misalignment of welds’ axes is developed. The method is applicable for welded thin-gauge plates with different geometry of welds on the face and root sides under tensile load. In the given calculation example, it was shown that the stresses reach their maximum value in the zone of transition from the root weld to the base metal which is farther from the axis of the face weld. The results of analytical calculations are in good agreement with the results obtained using the finite element method.
