Fatigue crack growth in thin notched woven glass composites under tensile loading. Part I: experimental [PDF]

open access: yes, 2011
Helicopter blades are made of composite materials mainly loaded in fatigue and have normally relatively thin skins. A through-the-thickness crack could appear in these skins.

Fatigue crack growth behaviour and life prediction for 2324-T39 and 7050-T7451 aluminium alloys under truncated load spectra [PDF]

open access: yes, 2010
This paper presents a study of crack growth behaviour in aluminium alloys 2324- T39 and 7050-T7451 subjected to flight-by-flight load spectra at different low- stress truncation levels. Crack branching was observed in the higher truncation levels for the

Evaluation of Surface Crack Development and Soil Damage Based on UAV Images of Coal Mining Areas

open access: yesLand, 2023
Coal mining is necessary for the development of society but at the same time causes ecological damage that must also be repaired based on science. In the arid and semi-arid regions of northwest China, surface cracks are one of the major geo-environmental

Micromechanisms of short fatigue crack growth in an Al-Si piston alloy [PDF]

open access: yes, 2014
The short fatigue crack growth behaviour of a model cast aluminium piston alloy has been investigated. This has been achieved using a combination of fatigue crack replication methods at various intervals during fatigue testing and post-mortem analysis of
