For welded joints of pipelines and elements of welded structures, including tubular ones, changes of section in weld zone are typical. The local rise of stresses or their concentration appears in the places of shape change. The level of concentration often plays a decisive role in determination of stress-strain state of structure in whole, has an effect on life at cyclic loads as well as influences the process of nucleation and propagation of cracks. This paper provides a review of works dedicated to the procedures for determination of maximum local stresses acting in the zone of stress concentration caused by geometry of welded joints of pipelines and tubular structures. 49 Ref., 1 Table, 4 Figures.
Keywords: pipeline welded joints, tubular structures, weld geometry, local stresses, stress concentration factor
