Prediction of the critical stress to crack initiation associated to the investigation of fatigue small crack [PDF]
Fracture and Structural Integrity, 2016 Fatigue design is of vital importance to avoid fatigue small crack growth in engineering structures. This study shows that the critical fatigue design stress can be defined below the usual endurance limit, considered in rules and codes.

Propagation threshold and crack closure of small fatigue cracks.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1990 The propagation behavior of fatigue crack from pre-cracks in smooth or notched specimens of a low-carbon steel was studied. The development of crack closure with crack growth was measured through the compliance method. An interferometric displacement gage was used to measure the opening displacement of surface cracks.

Fatigue crack surface area and crack front length: new ways to look at fatigue crack growth
MATEC Web of Conferences, 2018 This paper discusses the appropriateness of crack length as a reference dimension for fatigue damage. Current discussion on short crack versus long crack data is still divided between various approaches to model small crack growth.

Subsea jumper damage detection based on fractal analysis and modal characteristics
BrodogradnjaSubsea jumpers play a critical role in subsea oil and gas production. Structural damage such as cracks is inevitable in subsea jumpers due to the harsh marine environment (internal fluid flow corrosion, high temperature and pressure, etc.).

Controlling fatigue crack paths for crack surface marking and growth investigations [PDF]
Fracture and Structural Integrity, 2016 While it is well known that fatigue crack growth in metals that display confined slip, such as high strength aluminium alloys, develop crack paths that are responsive to the loading direction and the local microstructural orientation, it is less well ...
