Crack growth from internal defects and related size-effect in VHCF [PDF]
, 2017 It is well-known in the literature that fatigue cracks in VHCF originate from small internal defects. More than 95% of the total VHCF life is consumed in originating the so-called Fine Granular Area (FGA) around the small initial defect.

Waste to Wealth: Electrochemical Innovations in Hydrogen Production From Industrial Wastewater
Global Challenges, Volume 9, Issue 6, June 2025.There is increasing worry regarding the environmental impact of waste from hospital sewage, agricultural runoff, and industrial wastewater. Those wastes can contaminate water ecosystems, harming both human health and aquatic life. By employing an electrochemical method, we can treat these toxic substances in wastewater while simultaneously producing ...

Impact of bridge‐specific manufacturing conditions on fatigue of welded joints
Steel Construction, Volume 18, Issue 2, Page 89-98, May 2025.Abstract Box girders with steel cantilevers are often used in the design of composite steel bridges. The welded joints between the main girder and the transverse system are exposed to fatigue loading. Manual welds are common for which the manufacturing conditions can vary in terms of welding position and environmental settings. It is therefore intended

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 5, Page 2363-2380, May 2025.ABSTRACT Predicting very high cycle fatigue (VHCF) life in composites is challenging due to the lengthy testing times required by traditional methods. Ensuring compatibility between VHCF and high cycle fatigue (HCF) data presents an additional challenge.

Assessing the Very High Cycle Fatigue Behavior and Frequency Effect of Structural Steel Welds
Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 4, Page 1529-1541, April 2025.ABSTRACT The very high cycle fatigue behavior of S275J2+N flux‐core arc welded joints was investigated using the ultrasonic fatigue testing method at a loading frequency of 20 kHz. A bespoke specimen design featuring the weld toe was employed to more suitably represent in‐service welded joints than typical ultrasonic fatigue testing specimens.

Comparative Fatigue Analysis of Structural Steels Considering Welding and Surface Effects
Strain, Volume 61, Issue 2, April 2025.ABSTRACT There are limited data on the very high‐cycle fatigue for structural steel welds for over 10 million cycles. The purpose of this research is a fatigue performance comparison of the welds made of steels S355JR+AR and S275JR+AR. The goal of reaching the gigacycle fatigue domain is achieved using the ultrasonic fatigue testing at 20 kHz.
