DOI: 10.1016/j.apor.2017.05.012
Abstract: Abstract Offshore pipelines operating under high pressure and temperature are subjected to upheaval buckling. Pipeline behaviour in upheaval buckling depends on a number of factors including the shape of pipeline imperfection, installation stresses, loading types,… read more here.

DOI: 10.1016/j.apor.2020.102232
Abstract: Abstract Upheaval buckling may occur for subsea pipelines laid on the seabed with topographic step imperfection under high temperature. In order to predict the post buckling behaviour of upheaval buckling, a finite element model of… read more here.

DOI: 10.1016/j.engstruct.2017.06.027
Abstract: Abstract For pipelines with vertical imperfection, upheaval buckling may occur if the axial compressive force reaches the critical axial force of upheaval buckling. The critical axial force is sensitive to the pipeline imperfection and previous… read more here.

DOI: 10.1016/j.marstruc.2018.03.010
Abstract: Buried subsea pipelines under high temperature conditions tend to relieve their axial compressive force by forming localised upheaval buckles. This phenomenon is traditionally studied as a kind of imperfect column buckling problem. We study upheaval… read more here.

DOI: 10.1016/j.oceaneng.2016.12.006
Abstract: Abstract Offshore pipelines are often buried to protect the pipeline from external loads and upheaval buckling. Models for pipe uplift resistance in clay soils are based predominantly on homogenous backfill conditions. In practice, however, there… read more here.

DOI: 10.1016/j.oceaneng.2020.108220
Abstract: Abstract Subsea pipelines with a free suspended span segment may be subject to upheaval buckling under high temperature, which may lead to a failure mode such as local buckling, fracture and fatigue. Mathematical models are… read more here.
