Temperature, initial slope imperfections, and downward restraints on a pipeline all affect its propensity for upheaval buckling. A restrained pipeline is subject to compressive loads as the ...

An engineer has designed a model to guide better design of thin-walled structures, like planes, cars and submersibles, to avoid catastrophe like sudden collapse due to buckling. A University of ...

Long subsea pipelines, never laid in a perfectly straight line to begin with, tend to move over time. It’s a problem exacerbated by the high-temperature, high-pressure conditions in which pipelines ...

Roberto Ballarini, University of Houston Thomas and Laura Hsu Professor and department chair of Civil and Environmental Engineering, is leading the effort to predict the detrimental effects of ...
