Resumen:
To ensure enhanced HDPE linersstructural integrity, current design guidelines forplastic liners must be improved. The latter impliesto perform a more realistic non-linear analysis to assessthe structure?s capacity for design or evaluationpurposes. On one hand, the whole deformationprocess developed during the buckling event, includingdepressurization rate and real layout of thepipeline have to be considered. On the other hand,stress-strain material nonlinearity, deformation characteristicsassociated with viscoplasticity and environmentaleffects upon material?s properties have tobe also taking into account from here on
