Abstract
The method for theoretical prediction of service life of welded joints under bifrequency cyclic loading using Palmgren-Meier's hypothesis of linear summation of fatigue damage is considered. It is shown that this calculation procedure makes it possible to obtain appropriate estimates of service life of the joints requiring no additional experimental studies.
