Fatigue Testing of Carbon Fibre Reinforced Polymers under VHCF Loading

Procedia Materials Science, 2013
AbstractThe rapidly developing market for high strength and high stiffness carbon fibre reinforced polymers (CFRP) among others demands for reliable damage evaluation methods at very high cycle fatigue loading (VHCF). Due to the anisotropic nature of continuous fibre reinforced composites, fatigue damage is initiated in various failure modes.

Effect of Stress Ratio on Very High Cycle Fatigue Properties of PM‐HIPed Inconel 625

Fatigue &Fracture of Engineering Materials &Structures, Volume 48, Issue 8, Page 3593-3610, August 2025.
ABSTRACT This study investigated the impact of stress ratio on the fatigue performance and fatigue crack initiation characteristics of PM‐HIPed Inconel 625 in the very high cycle regimes. Ultrasonic fatigue tests, operating at a frequency of 20 kHz, were conducted on PM‐HIPed Inconel 625 samples under stress ratios of R = −1 and 0.1 up to the ultimate ...

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

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 ...
