Design and Development of an Accessible Clip Gauge Extensometer for CMOD Measurement in Fracture Mechanics

open access: yesEngineering Reports, Volume 8, Issue 2, February 2026.
A low‐cost clip gauge extensometer for crack mouth opening displacement was developed from accessible procedures and materials. Accuracy and repeatability comparable to commercial devices were demonstrated in calibration and fracture tests, enabling reliable measurement in CT specimens for resource‐constrained laboratories.

Flow accelerated preferential weld corrosion of X65 steel in brine [PDF]

open access: yes, 2014
Preferential weld corrosion (PWC) remains a major operational challenge that jeopardizes the integrity of oil and gas production facilities. It is the selective dissolution of metal associated with welds, such that the weld metal (WM) and / or the ...

Fitting of mechanical material behaviour of structural steel for numerical modelling

open access: yesSteel Construction, Volume 19, Issue 1, Page 83-98, February 2026.
Abstract Numerical simulations are widely used in structural engineering research, and validated models enable the efficient expansion of datasets without costly additional testing. They allow the investigation of alternative geometries and loading scenarios beyond those covered by experiments.

Computational and Experimental Analyses of the Synergistic Corrosion Inhibition of Green Phytochemicals Found in Yellow Bush in Acidic Media

open access: yesEngineering Reports, Volume 8, Issue 1, January 2026.
Synergistic interaction was observed to exist between terpineol, 1,5,9‐undecatriene‐2,6,10‐trimethyl‐(Z), and hexadecanoic acid‐methyl ester present in yellow bush. Yellow bush (YB) reduced acidic corrosion of API 5 L X65 steel, achieving optimum inhibition efficiency (IE) of 77.53% at 40 ppm, 89.99 at 60 ppm from WL, EIS and Tafel plots.
