Phase-field models for fatigue crack growth [PDF]
Theoretical and Applied Fracture Mechanics, 2019 We introduce a class of models based on near crack tip degradation of materials that can account for fracture growth under cyclic loads below the Griffith threshold. We incorporate the gradual degradation due to a cyclic load through a flow equation that decreases spatially varying parameters controlling the fracture toughness in the vicinity of the ...

A Crack Propagation Method for Pipelines with Interacting Corrosion and Crack Defects
Sensors, 2022 Corrosion and crack defects often exist at the same time in pipelines. The interaction impact between these defects could potentially affect the growth of the fatigue crack.

Reconstruction of fan blade dynamic loading prior to its fracture
Вестник Самарского университета: Аэрокосмическая техника, технологии и машиностроение, 2022 To maintain the functionality of fan blades, it is important to know the distribution of dynamic stresses in the blade, their amplitude and vibration frequency. Understanding of the dynamic loading pattern will allow us to determine under what conditions

Fretting fatigue crack propagation rate under variable loading conditions [PDF]
Fracture and Structural Integrity, 2016 Fretting fatigue experiments aim to represent industrial problems and most of them endure variable loading. Being able to assess lifetime of assemblies, especially for low propagation rate conditions, is essential as experimental validation is often ...

Fatigue crack behaviour : comparing three-point bend test and wedge splitting test data on vibrated concrete using Paris' law [PDF]
, 2017 The fatigue behaviour of concrete has become more important for the design of constructions due to the desire to build slimmer structures, which are more sensitive to fatigue loading.

A predictive fatigue life model for anodized 7050 aluminium alloy [PDF]
, 2013 The objective of this study is to predict fatigue life of anodized 7050 aluminum alloy specimens. In the case of anodized 7050-T7451 alloy, fractographic observations of fatigue tested specimens showed that pickling pits were the predominant sites for ...
