Modeling of creep-fatigue interaction effects on crack growth at elevated temperatures

open access: yesMATEC Web of Conferences, 2018
The well-known load frequency effect on creep-fatigue crack growth is explained by the interactions between fatigue and creep loading and is quantified using the concept of plasticity-induced crack closure.

Analysis of the Fatigue Crack Propagation Process of the Stress-Absorption Layer of Composite Pavement Based on Reliability

open access: yesApplied Sciences, 2018
The stress-absorption layer in cement concrete pavement delays the development of reflection cracks and is good at fatigue resistance. Laboratory investigations of the anti-crack performance of the high viscous asphalt sand stress-absorption layer ...

Effects of surface oxide layer on fatigue crack propagation properties of submicrometer-thick copper films

open access: yesNihon Kikai Gakkai ronbunshu
Fatigue failure involves fatigue crack initiation and propagation processes. In bulk metals, the fatigue crack initiation process is strongly affected by a dissimilar surface layer, while the fatigue crack propagation process is less affected.

Analysis of Fatigue Crack Propagation of an Orthotropic Bridge Deck Based on the Extended Finite Element Method

open access: yesAdvances in Civil Engineering, 2019
As one of the most fatigue-sensitive parts of an orthotropic steel bridge deck, the weld between the U-rib and the top deck is prone to fatigue cracking under the actions of the stress concentration, welding residual stress, and vehicle load.

Multiaxial fatigue crack path prediction using critical plane concept [PDF]

open access: yesFracture and Structural Integrity, 2016
Prediction of fatigue crack orientation can be an essential step for estimating fatigue crack path. Critical plane concept is widely used due to its physical basis that fatigue failure is associated with certain plane(s). However, recent investigations

Modelling probabilistic fatigue crack propagation rates for a mild structural steel [PDF]

open access: yesFracture and Structural Integrity, 2015
A class of fatigue crack growth models based on elastic–plastic stress–strain histories at the crack tip region and local strain-life damage models have been proposed in literature.

Fatigue damage evaluation of 316LN stainless steel using acoustic emission monitoring

open access: yes工程科学学报, 2018
The initiation and growth of fatigue cracks usually lead to serious fatigue failure of steel structures such as pressure vessels and pipelines. Therefore, for the safety and reliability of engineering structures, monitoring the fatigue crack growth and ...
