Numerical investigation of the cold-formed I-beams bending strength with different web shapes

Fracture and Structural Integrity, 2022
The wide use of cold-formed sections (CFS) in the field of steel constructions, favored by the multiple advantages they offer (lightness, ease of installation, etc.), has led us to reflect on a new process for manufacture of metal beams allowing the ...

Pre‐failure behavior of continuous post‐tensioned and post‐grouted beam in case of tendon failure

Structural Concrete, EarlyView.
Abstract Grouted tendons are a common solution for long‐span bridge structures. The grout provides bond and corrosion protection for prestressing steel. However, if the grouting is defective, corrosion of the prestressing steel may initiate and eventually lead to tendon failure.

Dielectric Barrier Discharge Plasma Deoxidation of Natively Oxide Layer of Copper Powders in a Fluidized Bed

Advanced Engineering Materials, Volume 28, Issue 12, 17 June 2026.
This paper presents a novel approach to reducing oxide layers on metal powders using low‐temperature hydrogen dielectric barrier discharge plasmas at atmospheric pressure. Unlike conventional hydrogen‐plasma reductions, the powders do not contact the plasma directly.

Experimental Factors and Techniques for Pool Boiling Heat Transfer Enhancement: A Critical Review

Heat Transfer, Volume 55, Issue 4, Page 2201-2232, June 2026.
ABSTRACT This review presents a comprehensive assessment of active strategies for enhancing pool boiling heat transfer, with a focus on techniques that do not rely solely on the boiling surface modification. It examines a broad range of methodologies including fluid additives, external fields, mechanical interventions, and thermal‐geometric tuning that
