Crack growth rate prediction based on damage accumulation functions for creep-fatigue interaction
Fracture and Structural Integrity, 2020 The present study is concerned with formulation of a model for the creep–fatigue crack growth rate prediction on the base of fracture damage zone concepts. It is supposed that crack growth rate can be determined by integration of damage accumulation rate

Fatigue Crack Growth Rate Analysis in a Titanium Alloy
Key Engineering Materials, 2008 Reliable prediction of fatigue crack growth rates in aerospace materials and components underpins the so-called defect-tolerant approach to lifing. In this methodology the presence or appearance of defects and cracks in components is accepted. However, safe operation is guaranteed by regular inspections and health monitoring, and ensuring (by means of ...

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

Prediction of growth rate of short fatigue cracks.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1987 A method based on crack closure was proposed to predict the growth rate of short fatigue cracks in either smooth specimens or notched specimens. The material properties used in this prediction were the growth behavior of long cracks and the fatigue limit of smooth specimens.

Influence of High Pressure Drop Rates on Fatigue Crack Growth
Chemical Engineering & Technology, 2022 AbstractHydraulic components in mobile machines are subjected to varying conditions and loads, which limit their lifetime. In particular, high pressure drop rates are suspected to increase fatigue crack growth rates. Existing studies on the fluid‐structure interaction inside fatigue cracks during fast pressure drops do not explain increased crack ...
