Evaluation of the ultimate stresses in a cycle for welded structures with high residual stresses based on test results for small specimens without residual stresses

We propose an equation for the evaluation of the fatigue limits of welded joints of low-carbon and low-alloy steels with high residual stresses based on the results of testing of small specimens without residual stresses. The independence of the amplitude of stresses on the mean stress in a cycle is proved for welded joints with high residual stresses. __________ Translated from Problemy Prochnosti, No. 2, pp. 66–81, March–April, 2008.
