Timber offers generally good performances against fatigue loading. However, little is known about the fatigue performance of adhesively bonded wood samples. In this thesis, the influence of the adhesive properties on the fatigue performances was investigated on three different types of sample (pure adhesive film, lap-shear and 4 points End-Notched Flexure). The results show that ductile adhesives can be loaded a higher number of cycles than brittle adhesives. However, once a crack is present, its propagation is faster and require less energy if a ductile adhesive system is used.
