Abstract
A methodology and results of fatigue life assessment of a structure containing continuous welding joint under random kinematic loading taking into account the influence of residual welding stresses have been presented. Realizations of random stress processes in the welding joint area and dependences for amplitude repeatability of reduced regular stress cycles have been constructed on the basis of numerical simulation. Characteristics of durability of the structure by two theories of accumulation of fatigue damages have been determined. Significant influence of residual welding stress levels on durability is shown.
