N2 - In the present paper, the fatigue damage behavior of fiber metal laminates based on a titanium alloy and glass fiber-reinforced polymers (Ti/GFRP) as the Ti/FRP system was investigated. Static tensile tests and tensile-tensile fatigue tests were conducted on open hole specimens of these laminates manufactured by bonding Ti alloy sheets and GFRP. The crack initiation, crack growth and delamination were observed, and the crack growth in Ti skin layer, the transverse cracks in GFRP core and the stiffness degradation were focused. From the experimental evidence, it was shown that the crack initiation and growth in the Ti skins played a key part onto the fatigue behavior and that crack growth rate in the Ti skin layers of Ti/GFRP laminates kept almost constant although the fatigue cycle increased.
