Abstract :

Glass Laminate Aluminum Reinforced Epoxy consist of three or more layers of Al alloy and fibers alternatively. Fatigue crack growth rates in notched fiber-metal laminates under constant amplitude fatigue loading were studied numerically and were compared with them in monolithic 2024-t3 Al alloy plates, it’s shown that the fatigue life of Glare is more longer than monolithic 2024-t3 Al alloy plate and crack growth rate in Glare panel remain constant mostly even when crack is long. stress intensity factor for given crack tip position is determined by a finite element method in ABAQUSE system.
