“…In this study, the I-shaped weld was also idealized as a rectangular shape, as well as the original and repaired part of the weld ( Figure 1 ), and the crack was located in the center of the weld. In [ 25 ], researchers have demonstrated that the mechanical properties of the heat-affected zone have a negligible effect on the stress concentration at the crack tip when the crack tip is located in the center of the weld. However, if the crack tip is located in or near the heat-affected zone, the properties of the heat-affected zone have to be taken necessarily into account [ 26 ].…”

The objective of this work was to investigate the fracture behavior of a heterogeneous I-shaped welded joint in the context of yield load solutions. The weld was divided into two equal parts, using the metal with the higher yield strength and the metal with the lower yield strength compared to base metal. For both configurations of the I-shaped weld, one with a crack in strength in the over-matched part of the weld and one for a crack in the under-matched part of the weld, a systematic study of fracture toughness SE(B) specimen was carried out in which the crack length, the width of the weld and the strength mismatch factor for both weld metals were varied, and the yield loads were determined. As a result of the study, two mathematical models for determination of yield loads are proposed. Both models were experimentally tested with one strength mismatch configuration, and the results showed good agreement and sufficiently conservative results compared to the experimental results.

“…Examples of such simplified studies is by Khalfallah [18] to assess the mechanical properties of welded tubes, or the analysis of welded tensile plates with a surface notch performed in [19]. Only a small amount of numerical research studies exist where material properties of a HAZ have been assumed to be different to the weld and the base material [2,20].…”

“…Most previous studies have focused on investigation of single cracks and analysis of the interaction of multiple cracks under linear-elastic and elastic-plastic fracture mechanics conditions [8][9][10][11][12][13][14][15][16][17]. There are only a few studies that have focused on multiple cracks interaction under creep regime [18][19][20].…”

In many practical situations, high-temperature structures and components contain more than one crack. An interaction of such multiple cracks has significant influence on the service life of structures and components. In this paper, the interaction of two identical parallel edge cracks in a finite plate subjected to the remote tension is numerically analyzed. The results show that interaction effect of multiple cracks at creep regime is obviously greater than at linear elastic regime. The intensity of creep crack interaction increases with increasing creep exponent m. The crack intensity and the crack interaction limit at creep regime depend on crack distance ratio d/a, crack width ratio a/W and creep exponent m.
