International audience; In this work, electrodynamic shaker was used to carry out vibration-based bending fatigue on specimens made with Ti-6Al-4V. Modal behaviour of symmetrical and unsymmetrical specimens were studied and especially the resonant frequency. This parameter makes it possible to define the rate of frequency change used to detect a change of physical properties of material due to the presence of crack for example. The impact of the geometry on the rate of frequency change is analysed and to support the analysis observations on crack growth were used to conclude on the impact of manufacturing defects.
