- Abstract
For welded joints of pipelines and elements of welded structures, including piped ones, changes in the weld zone section are typical. In places of shape change, a local increase in stresses or their concentration occurs. The degree of concentration often plays a decisive role in determining the stress-strain state of the structure as a whole, affects the service life under cyclic loads, and also affects the process of crack nucleation and propagation. This article provides a review of works on methods for determining the maximum local stresses acting in the zone of stress concentration caused by the geometric shape of welded joints of pipelines and piped structures.
