Finite Element Analysis of Propagating Buckles in Deep Water Pipelines
Andreas T. Katsounas and John Tassoulas, University of Texas
A finite element technique is developed for the analysis of propagating buckles in deep-water pipelines accounting for large deformation, elastoplastic material behavior and contact between regions of the interior wall of the pipe. The technique is applied to the analysis of buckle initiation, propagation and arrest in a pipe. Excellent agreement is found between analytical results and experimental data.
