Characterization of fatigue crack initiation and propagation in Ti-6Al-4V with electrical potential drop technique [PDF]
Electrical potential methods have been used in the past primarily to monitor crack length in long crack specimens subjected to fatigue loading. An attempt was made to develop test procedures for monitoring the fatigue crack initiation and the growth of ...

Fatigue Crack Growth Under Random Overloads with Retardation
MATEC Web of Conferences, 2016 A Monte Carlo simulation scheme is presented to study the behavior of fatigue crack propagation under random overloads. Overloads of Poisson flow with uniform distribution on base-line constant-amplitude cyclic loads are considered.

Advances on creep–fatigue damage assessment in notched components [PDF]
, 2017 In this paper, the extended Direct Steady Cyclic Analysis method (eDSCA) within the Linear Matching Method Framework (LMMF) is combined with the Stress Modified Ductility Exhaustion method and the modified Cavity Growth Factor (CGF) for the first time ...

Fatigue crack growth in a unidirectional SCS-6/Ti-15-3 composite [PDF]
An investigation was conducted to characterize and model the fatigue crack growth (FCG) behavior of a SCS-6/Ti-15-3 metal matrix composite. Part of the study was conducted using a fatigue loading stage mounted inside a scanning electron microscope (SEM).

A comparison of fatigue life prediction methodologies for rotorcraft [PDF]
Because of the current U.S. Army requirement that all new rotorcraft be designed to a 'six nines' reliability on fatigue life, this study was undertaken to assess the accuracy of the current safe life philosophy using the nominal stress Palmgrem-Miner ...

Plasticity induced crack closure in adhesively bonded joints under fatigue loading [PDF]
, 2015 The mean load of a cyclic loading has a large effect on fatigue crack growth rates in metallic materials and bonded joints. In metallic structures, this effect has been attributed to plasticity-induced crack closure, but little is known about the ...

The relationship between observed fatigue damage and life estimation models [PDF]
Observations of the surface of laboratory specimens subjected to axial and torsional fatigue loadings has resulted in the identification of three damage fatigue phenomena: crack nucleation, shear crack growth, and tensile crack growth.

ON CRACK CLOSURE IN FATIGUE CRACK GROWTH
, 1978 A brief review of the various forms of closure is given, and the relative importance of plasticity-induced closure and roughness-induced closure is considered. On the basis of the lack of a thickness effect and an insensitivity to R in the absence of closure it is concluded that plasticity-induced closure plays a relatively minor role in affecting the ...
