High‐Order Fiber Bragg Grating Corrosion Sensor Based on the Detection of a Local Surface Expansion

open access: yesStructural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023
This paper presents a fiber optic sensor for the detection of corrosion processes that occur on metal surfaces. In the proposed sensor design, a sensing fiber with an inscribed high‐order Bragg grating is attached to the observed metal surface. A broadening of high‐order Bragg grating spectral characteristics is observed and used to detect small and ...

On the Resistance to Buckling Loads of Idealized Hull Structures: FE Analysis on Designed-Stiffened Plates

open access: yesDesigns, 2022
In this paper, the buckling analysis on simply supported rectangular plates and stiffened panels is carried out. Three different plate thicknesses were proposed (i.e., 3 mm, 4 mm, and 5 mm).

Effect of AC interference on the corrosion behavior of cathodically protected mild steel in an artificial soil solution. Part I: Investigation on formed corrosion product layer

open access: yesMaterials and Corrosion, Volume 73, Issue 1, Page 45-54, January 2022., 2022
Investigations on the surface processes on cathodically protected mild steel during AC polarization have been performed. They utilized high‐speed potential measurements that have demonstrated the influence of the polarization parameters on the resulting alternating voltage.

Extracting true stresses and strains from nominal stresses and strains in tensile testing

open access: yesStrain, Volume 57, Issue 6, December 2021., 2021
Abstract Seemingly a simple task, the extraction of the flow curve (true stress vs. true plastic strain) from nominal stresses and strains in standard tensile testing still has its unsolved points. This study addresses two of them: (i) in materials without yield point phenomenon (or generally in the region of homogeneous plastic deformation), the true ...

Seismic Response of a Platform-Frame System with Steel Columns [PDF]

open access: yes, 2017
Timber platform-frame shear walls are characterized by high ductility and diffuse energy dissipation but limited in-plane shear resistance. A novel lightweight constructive system composed of steel columns braced with oriented strand board (OSB) panels ...

Study on the Pneumatic Lime Injection in the Electric Arc Furnace Process: An Evaluation on the Performance Benefits

open access: yessteel research international, Volume 92, Issue 9, September 2021., 2021
More than 1200 heats are used so as to investigate the benefits of the powder lime injection in a 90 t electric arc furnace (EAF) and compared with the traditional addition of lime in lumps. Savings above expectations are observed for electric consumptions and lime charged, also reducing CO2 emissions for both the production of structural and special ...
