Modeling and Experimental Aspects of Self-healing Bolted Joint through Shape Memory Alloy Actuators
(Sage Publications Ltd, 2011-09-01)
Bolted joints are a form of mechanical coupling largely used in machinery due to their reliability and low cost. Failure of bolted joints can lead to catastrophic events, such as leaking, train derailments, aircraft crashes, ...
Plasma immersion ion implantation: Influence on the rotating bending fatigue strength of AA 7050-T7451 aluminum alloy
(2017-10-01)
Failures in structural components due to cyclic loading are associated with the surface damage. The aircraft industry has been searched into the alternative coatings that enhance performance by reducing the environmental ...
Describing fatigue crack growth and load ratio effects in Al 2524 T3 alloy with an enhanced exponential model
(Elsevier B.V., 2012-08-01)
The fatigue crack behavior in metals and alloys under constant amplitude test conditions is usually described by relationships between the crack growth rate da/dN and the stress intensity factor range Delta K. In the present ...
Estudo de casos de seleção dos materiais e processos para a fabricação de fuselagens
(Universidade Estadual Paulista (Unesp), 2013-12-17)
This work proposes a study on the materials selections and processes for the manufacture of aircraft and showing a methodology to reduce the manufacturing cost. The DFMA can be understood as a methodology that aims at ...
Qualitative and quantitative characterization of aluminium alloys after corrosion testing
(Carl Hanser Verlag, 2001-06-01)
The 2024 and 7050 aluminium alloys used as aircraft components were subjected to laboratory corrosion tests in sodium chloride solution, Light-microscope examinations make it possible to characterise morphological aspects ...

Mechanical and microstructural characterization of laser-welded joints of 6013-T4 aluminum alloy
(Springer, 2015-01-01)
Laser beam welding may be used in the place of the traditional riveting process for the welding of the stringers to the skin in aircrafts. This work intends to investigate the mechanical behavior of laser-welded aluminum ...
Modeling and Experimental Aspects of Self-healing Bolted Joint through Shape Memory Alloy Actuators
(Sage Publications Ltd, 2014)
Electrochemical properties and nano-hardness of anodic oxide film grown over Al-Cu alloy
(2004-12-01)
Al-Cu alloy is largely employed in mechanical and aircraft industries. Usually aluminum and aluminum alloys are submitted to an electrochemical process called anodizing that consists on growing an oxide film on their ...
