Fatigue design of engineering structures is typically based on lifetime calculation using a
cumulative damage law. The linear damage rule by Miner is the universal standard for …

Very-high-cycle fatigue (VHCF) is the fatigue damage and failure beyond 10 7 loading
cycles. Crack initiation of VHCF for metallic materials is commonly from the interior of …

Ultrasonic fatigue testing is a resourceful (time-and cost-saving) approach to assess the
dynamic failure of materials in the gigacycle range (ie, when the number of cycles to failure …

Purpose Scholars mainly propose and establish theoretical models of cumulative fatigue
damage for their research fields. This review aims to select the applicable model from many …

The research on the Very High Cycle Fatigue (VHCF) response of materials is fundamental
to guarantee a safe design of structural components. Researchers develop models for the …

The fine granular area (FGA) plays a crucial role in the VHCF regime. However, so far, the
uniform understanding or conclusion about the formation mechanism of FGA has not been …

Rehabilitating corroded or seismically damaged reinforced concrete (RC) bridge columns
often involves replacing the longitudinal steel rebar. Welded joints offer a practical and …

Defects and microstructural inhomogeneity have been recognized to have a significant
impact on the fatigue performance of titanium alloys fabricated by laser powder bed fusion …

In light of the steel development trend—plainification and high performance, we designed a
gradient nanostructured plain steel with ultrahigh mechanical performance and exceptional …

This study aims to explore the very high cycle fatigue performance of GCr15 bearing steel
produced by two different melting routes by ultrasonic fatigue testing. The results show that …
