Safety assessment on girth welds of large-diameter X80 pipelines in water network area
Published 2023-10-01“…On this basis, the safety of pipeline welds at different locations in the soft soil settlement area was evaluated according to the Guide to Methods for Assessing the Acceptability of Flaws in Metallic Structures (BS 7910-2019). Meanwhile, the influence of external load conditions and weld misalignment was analyzed, which indicates that the increase of misalignment leads to an increase in the load ratio and toughness ratio used in the assessment, with the conservativeness reduced for the safety of pipeline. …”

Machine learning Hubbard parameters with equivariant neural networks
Published 2025-01-01“…Abstract Density-functional theory with extended Hubbard functionals (DFT + U + V) provides a robust framework to accurately describe complex materials containing transition-metal or rare-earth elements. It does so by mitigating self-interaction errors inherent to semi-local functionals which are particularly pronounced in systems with partially-filled d and f electronic states. …”

Analysis on the Difference of Impact Response between Single Coal-Rock Particle and the Box Structure-Based Tail Beam
Published 2021-01-01“…Firstly, through the construction and analysis of the impact theoretical model of the coal-rock particle and metal plate, it is found that the complex box structure of the tail beam makes it extremely difficult to establish the impact theoretical model of the coal-rock and box structure-based tail beam, so it is impossible to directly study the response of the box structure-based tail beam when the coal-rock impacts on the box structure-based tail beam by the theoretical method. …”
