Shallow and insufficient soil support may lead to upheaval buckling of heated pipelines in shore approach areas. This article presents a numerical model to simulate the thermomechanical buckling of ...

A new methodology assesses the risk of upheaval buckling and determines the required profile of the trench bottom as a bed for both subsea and onshore pipelines. A new methodology assesses the risk of ...

Buried pipelines are critical infrastructure that underpin global energy and resource distribution networks. Their structural integrity is continually challenged by geohazards, ranging from gradual ...

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 ...

Pipe-soil interaction is a crucial problem in the global buckling design of submarine pipeline under thermal stresses. Soil resistance acting on the pipelines determines the deformation shape and ...

Linear finite-element analysis does not provide enough information about buckling to make correct design decisions, especially when designing lightweight components ...
