Boundary selectivity of crack paths in corrosion fatigue of stainless steel [PDF]
, 2008 Stress corrosion and corrosion fatigue cracks are frequently very branched and there have been extensive attempts to define the characteristics of crack-stopping features. EBSD has been used to examine the full length (~8mm) of a corrosion fatigue crack

Fatigue of friction stir welded 2024-T351 aluminium alloy
, 2002 Fatigue failure characteristics of friction stir welds in 13mm gauge 2024-T351 plate have been assessed. Failure occurred from either the weld region (nugget/flow arm) or from the material immediately surrounding the weld.

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 ...

Short crack initiation and growth at 600 °C in notched specimens of Inconel718
, 2003 The natural initiation and growth of short cracks in Inconel®718 U-notch specimens has been studied at 600 °C in air. U notches were introduced through broaching, and hardness traces and optical microscopy on cross-sections through the U notch broaching ...

Modeling of crack bridging in a unidirectional metal matrix composite [PDF]
The effective fatigue crack driving force and crack opening profiles were determined analytically for fatigue tested unidirectional composite specimens exhibiting fiber bridging. The crack closure pressure due to bridging was modeled using two approaches;

Multiaxial fatigue crack path prediction using critical plane concept
Fracture and Structural Integrity, 2015 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).

Experimental Study on Fatigue Crack Detection of Marine Riser Based on Magnetic Dipole
Shiyou jixie, 2019 To obtain the fatigue crack length of the riser and determine its fatigue damage state, the magnetic memory signals of the X80 pipeline steel in the fatigue crack initiation, propagation and fracture stages are detected by metal magnetic memory detection.
