Tensile Fracture Behavior of Corroded Pipelines: Part 2—Numerical Simulation Based on Monte Carlo Method
Published 2020-01-01“…Inspired by the surface topology by scanning electronic microscopy (SEM) and the scattered distribution of test data, a computational procedure based on the Monte Carlo simulation method was developed in this paper to understand the randomness of the crack propagation process and the performance degradation mechanism of the corroded pipelines. A total of 2700 random samples, which contain three corrosion rates of 15%, 45%, and 70% with each corrosion rate having three variances of 0.02 mm, 0.06 mm, and 0.10 mm, were generated and then were mapped to the shell section of the FE model. …”

High-resolution analysis of hydraulic response characteristics of silted stormwater pipeline and manholes in urban catchments using GASM-TranGRU and CFD-DEM
Published 2025-12-01“…The pipe with a transverse siltation intensity of 10% showed an 8.07% reduction in the maximum overflow flow rate, whereas the pipe with a longitudinal siltation intensity of 5.2% exhibited a 15.09% reduction, suggesting that longitudinal siltation intensity has a more significant impact on pipeline failure.Conclusion:The research results provide technical support for the diagnosis of pipeline siltation and flood risk assessment considering the change of water level in the manhole and the inlet and outlet flow velocity of the pipe section.…”

Des vestiges liés à la phase de construction de l’aqueduc de la Brévenne à Limonest (Métropole de Lyon) ?
Published 2023-12-01“…At Dardilly and Lentilly, the ditches are intersected by the pipeline’s installation trench. The dating of ceramics and of a complete tegula discovered at Limonest corroborates the likelihood that they were dug prior to or contemporary with the construction of the aqueduct.The similarity of these ditches, their repetition at regular intervals and their location on several sections of the aqueduct route suggest a global strategy relating to the construction of the aqueduct rather than to occasional repairs. …”
