The influence of ply-drop position in thickness direction under fatigue loading (R = -1) has been studied. Two configurations with different ply-drop positions which drop from 20 to 12 plies have been compared in mechanical tests and finite element simulations to identify the damage modes, spots and kinetics before final failure.
