Spatial characteristic of temperature distribution and material flow behaviors during bobbin tool friction stir welding: a computational fluid dynamics study

This study establishes a fully coupled thermo-mechanical-fluid computational fluid dynamics model to demonstrate that a Front-Peaked Contact Pressure Model most accurately predicts the asymmetric temperature distribution and complex material flow behaviors in bobbin tool friction stir welding, revealing that high-pressure zones ahead of the tool drive hot material from the advancing side to the retreating side.

Study on Bonding Performance of Double-Layer CFRP-Steel Interface under Salt Erosion and Freeze-Thaw Environments

This study employs a fully coupled finite element model in COMSOL Multiphysics to demonstrate that a double-layer CFRP-steel reinforcement system significantly enhances interfacial durability and load-bearing retention under combined salt erosion and freeze-thaw conditions, while identifying optimal design parameters such as a 200–250 mm bond length and 2.0 mm adhesive thickness.

Geotechnical Assessment of Slope Instability Triggered by Solid Waste Dumping in Engineered Landfills and Informal Waste Dumps

This paper analyzes the geotechnical mechanisms behind slope failures caused by solid waste dumping in both engineered landfills and informal dumps, drawing on global case studies to argue that conventional stability frameworks are often inadequate for waste masses and proposing practical measures to mitigate instability risks.
