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 performance criteria for CFRP Reinforcements Based on RC behavior in civil construction

Journal of Asian Architecture and Building Engineering
This study aims to develop fatigue performance criteria for Carbon Fiber Reinforced Polymer (CFRP) reinforcements, considering the mechanical behavior of Reinforced Concrete (RC) structures. Fatigue tests were conducted to create S-N and ε-N curves based

Influence of defects on the very high cycle fatigue behaviour of forged aeronautic titanium alloy

MATEC Web of Conferences, 2014
This paper is focused on fatigue failure of forged aeronautic titanium alloy Ti-6Al-4Mo under VHCF loading. Continuous fatigue tests were carried out in gigacycle fatigue regime (up to on 1010 cycles) on specimens machined from real aircraft compressor ...

Gaussian specimens for VHCF tests: Analytical prediction of damping effects

International Journal of Fatigue, 2016
Abstract Experimental tests investigating Very-High-Cycle Fatigue (VHCF) properties of materials are commonly performed with ultrasonic testing machines which allow for a significant reduction of testing time but induce a relevant temperature increment in specimens. In particular, due to the large volume of material (risk-volume) under test, Gaussian

Comparability of Fatigue Strength and Life Estimation of a CF‐PEKK Composite Under Low and Ultrasonic Frequencies Using Time‐Temperature‐Based Approaches

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.
