Comparative Natural Gas Venting Pipe Damage Stress Prediction Study Based on Multiple Machine Learning Methods

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
Stress damage in operational natural gas venting pipes is a complex issue that requires pipeline designs tailored to specific operational conditions. This study aims to accurately predict operational stress during the blow‐off process by leveraging design and operational parameters to assess potential pipeline damage. Five machine learning (ML) methods—

A New Approach to Single‐Step Fabrication of TiOx‐CeOx Nanoparticles

Small Science, Volume 4, Issue 11, November 2024.
A novel approach for the synthesis of TiOx‐CeOx NPs based on a gas aggregation cluster source equipped with a single segmented target is presented. Analytical results from particles synthesized at different conditions reveal the highly defective nature of the particle surface as well as the presence of various morphologies.

Experimental and numerical determination of the fatigue notch factor in as‐built wire arc additive manufacturing steel components

Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4372-4389, November 2024.
Abstract Parts manufactured by wire arc additive manufacturing (WAAM) are characterized by a peculiar surface morphology, namely, surface waviness, that negatively affects the fatigue performance. To exploit the full potential of WAAM and minimize the need for postproduction work, it is crucial to utilize the components in the as‐built state.

Dynamic behavior and cumulative deformation analysis of ferronickel slag-clay mixtures under cyclic loading

Case Studies in Construction Materials
Ferronickel slag, an industrial byproduct, shows potential as road subgrade filler after modification. However, its permanent deformation accumulation under cyclic traffic loads may cause rutting and cracking, compromising long-term performance. Existing
