Abstract Mixed-mode fatigue crack growth behavior of an automotive adhesive bonding system (AA5754O- A951-BM4601) has been investigated using a compound compact mixed-mode specimen. The test was performed under load control with 0.1 R ratio and 3Hz frequency. A long-distance moving microscope was employed to record the real-time length of the fatigue crack in the adhesive layer during testing. The strain energy release rate components of the crack were analyzed by finite element method. The pure...

Abstract Practical fatigue life prediction methods using computer aided engineering (CAE) for adhesively bonded joints are needed to reduce the risk of potential fatigue failures and unnecessary over-designs for automotive body structures. This paper presents an investigation on the tensile and fatigue behaviors of adhesively bonded lap shear and coach peel joints for A5754-O. From suspended tensile tests, macroscopic cracks were found in the adhesive layer of the lap shear joints before the joi...

AbstractFatigue and corrosion damage are the major concerns of automotive adhesive joints, yet literature reports few works about the in situ fatigue durability of adhesive joints in corrosive environment. This study presents an investigation on the fatigue durability of automotive adhesive single lap joints by an in situ corrosion fatigue test. The joints were manufactured with commercial coated AA5754-O aluminum sheets bonded by a toughened epoxy structural adhesive. An in situ corrosion chamb...
