Initiation and growth of micro-cracks under cyclic loading

open access: yes, 2008
The early stages of fatigue damage causing nucleation of micro-cracks, followed by their growth and coalescence to macro-cracks have been studied in single and multi-phase steels.

Micro-mechanical behaviors of granite under cyclic heating/cooling conditions investigated by GBM3D

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
During the exploitation of hot dry rock, the surface of the convective heat transfer channel undergoes repeated cycles of heating and cooling. Investigating the microstructure of granite after such cyclic thermal treatments is crucial for ensuring the ...

A predictive fatigue life model for anodized 7050 aluminium alloy [PDF]

open access: yes, 2013
The objective of this study is to predict fatigue life of anodized 7050 aluminum alloy specimens. In the case of anodized 7050-T7451 alloy, fractographic observations of fatigue tested specimens showed that pickling pits were the predominant sites for ...

Development of A Novel Adaptive Range Strain Sensor for Structural Crack Monitoring

open access: yesJournal of Marine Science and Engineering, 2022
Ocean platforms that are under complex sea conditions and loads for long periods are prone to fatigue cracks. These cracks may lead to large deformations, even displacement, of the platform, and should be monitored to ensure engineering safety.

Automatic detection and evaluation of solar cell micro-cracks in electroluminescence images using matched filters

open access: yes, 2016
A method for detecting micro-cracks in solar cells using two dimensional matched filters was developed, derived from the electroluminescence intensity profile of typical micro-cracks. We describe the image processing steps to obtain a binary map with the

Microbes: A Remedy for Micro Cracks of Concrete

open access: yesInternational Journal For Multidisciplinary Research
Crack formation is a very common phenomenon in concrete structures, which allows the entry of water and different type of chemicals into the concrete through the cracks and decreases their durability, strength and, which also affect the reinforcement when it comes in contact with water, CO2 and other chemicals. For repairing the cracks developed in the

IRREVERSIBLE THERMAL EXPANSION OF REPLICATED ALUMINIUM FOAM

open access: yesActa Metallurgica Slovaca, 2018
Irreversible thermal expansion of large items made of the replicated aluminium foam was detected during the extraction of soluble filler from Al-NaCl composite. Sources of the phenomenon were investigated The expansion discovered was caused by incomplete
