Abstract

This paper presents the numerical results of a structural integrity assessment of a large-scale four-point bending test performed on a repair welded Esshete 1250 pipe. In this work, a finite element (FE) model of the test was created in ABAQUS, and the weld residual stress was introduced to the model by an iterative technique. The Rousselier model was employed to describe the ductile fracture of test specimen including crack initiation position and growth. The prediction of final crack growth obtained from this analysis is compared with the results obtained from the fracture mechanics approach and the test outcome.
