AA7050-T7451 aluminum alloy is one of the most used material in aeronautical applications due to its high strength/density ratio and good fatigue resistance. More recently the AA2050-T84 alloy was introduced due to its ...

The aim of this study was to analyze the effect of successive TIG (tungsten inert gas) welding repairs on the reverse bending fatigue strength of AISI 4130 steel, which is widely used in components critical to the ...

Multiple layer systems of coatings are considered to have larger resistance to crack propagation in comparison to coatings with simple layer. With regard to fatigue, it is possible to improve the resistance of a component ...

Fatigue crack usually initiates at welded joints of structural elements. For a high-responsibility aeronautic component, called Motor-Cradle - critical to the flight safety -, successive weld repairs are carried out toward ...

Historically Brazil has been solidifying as an important generator of technologies for the aircraft production (MONTINI et. al, 2019). The Brazilian aeronautical sector has dozens of small companies, aircraft manufacturers ...

Actually in Brasil there there is a fleet around 1500 agricultural aircraft working on different aplications. The spray aplication by na airplane of crop defenses is increasing on the last years, generating a demand on ...

It is well known that fatigue behaviour is an important parameter to be considered in mechanical components subjected to constant and variable amplitude loadings. In combination with corrosion phenomenon, fatigue effects ...
