✦ Synopsis

Reports indicate that the joint geometry and loading configuration affect the crack growth behaviour of specimens. In an attempt to study the above effect, three specimen geometries are selected; cruciform joint under tension (CJT), side end notch under tension (SENT) and under three-point bending (SENB3) load. Results show that all three geometries have different fatigue strength and fracture mechanics parameters, although their weld-metal chemistry and mechanical properties are the same. Further tests are needed to establish this relationship quantitatively.

## Abstract The numerical fatigue assessment of seam welded joints is of significant importance in automotive industry. In order to use the fatigue concepts, which are available in the literature, in series calculations, they usually have to be implemented into commercial software programmes. In th

## Abstract Tubular space trusses for bridge applications use thick‐walled tubes. The reduction in fatigue resistance due to geometrical size effects is thus an important issue. In order to carry out a thorough study, both fatigue tests on large‐scale specimens and advanced 3D crack propagation mod
