A finite element technique has been developed and implemented for the analysis of buckle initiation and propagation in deep-water pipelines accounting for large deformation, elastoplastic material behavior and contact between regions of the interior wall of the pipe. Buckle propagation speeds are obtained and the dynamic characteristics of the buckles are studied. For the analysis of a pipe surrounded by water, fluid-structure interaction is treated in a approximate manner. Excellent agreement is found between analytical results and experimental data.
