THE EFFECT OF MISALIGNMENT ON THE FATIGUE STRENGTH OF WELDED CRUCIFORM JOINTS
Abstract— The effect of axial misalignment on the fatigue strength of load-carrying transverse cruciform welded joints was investigated using experimental and fracture mechanics methods. WhereExpand

A specimen for studying the resistance to ductile crack propagation in pipes
The paper describes a novel DCB-like specimen designed for studying the resistance of running axial cracks in pipelines. It is long enough for steady-state conditions to govern a large proportion ofExpand

TWI biaxial test program: 1984–1994
The influence of biaxility on the upper-shelf, lower-shelf and the ductile-to-brittle transition regimes has been investigated. A total of 16 biaxial wideplate tests have been conducted. In addition,Expand

A Single Specimen CTOA Test Method for Evaluating the Crack Tip Opening Angle in Gas Pipeline Steels
Failure information from recent full-scale burst experiments on modern TMCP gas pipeline steels having a yield strength level of 690MPa and higher has shown that the CTOA fracture criterion can beExpand
