... software. Soil was modeled in an Eulerian framework and the pipe in a Lagrangian framework. Strain softening behavior and strain rate effects on undrained shear strength of clay was incorporated in ABAQUS FE software using user subroutines written in FORTRAN. The variation of undrained shear strength...

... an opportunity to make accurate assessments of the severity of SCC in a pipeline segment and to characterize the history of that segment. Previous work had shown the importance of strain rate and pressure fluctuations in promoting SCC. On that basis, Enbridge Pipeline, Inc. initiated a review of their system...

...) specimens. The study included numerical simulation of the dynamic response of back-slotted specimens. The significance of the back-slot in altering the stress/strain field ahead of the propagation crack is discussed. The numerical simulation was also used to determine the strain rate in the “process zone...
