Avaliação do comportamento em fadiga de juntas estruturais de ligas de Al2024T3 coladas com adesivo epóxi

Abstract: Ligas de alumínio são extensamente usadas em partes aeronáuticas devido às boas propriedades mecânicas e baixa densidade. Estas partes devem ser unidas para formar conjuntos maiores. Uma junta estrutural é definida como um segmento de estrutura que provê um meio de transferir carga de um elemento estrutural para outro. A maioria das juntas aeronáuticas é mecanicamente fixada com múltiplos prendedores (parafusos ou rebites). Estas juntas apresentam uma alta concentração de tensões ao redor do prendedor, porque … Show more

“…Different from isotropic materials, composite material properties change according to the fiber orientation, showing higher stiffness and strength on its parallel direction, when considering unidirectional reinforcements 10 . Furthermore, the secondary moment caused by load application eccentricity overload the fasteners, which can lead to excessively tensioned couplings 2 and, in joints with gaps between hole and fasteners, rotate the fixer, resulting in uneven load distribution along the test specimen thickness 1 . The higher the bending moment applied on the fastener, the higher the chance of its deformation and also the bearing on the hole wall 2 .…”

“…Structural joints are one of the biggest challenges in structural design 1 , and therefore, relevant for mechanical tests and stress analysis 2 . Stress concentration occurs on its force transference points and the attachment element and/or the respective joint nearby regions are always pre-deformed 3 .…”
