This work is initially devoted to study the cracking behaviour of a small composite wind turbine blade. In order to choose material, the blade is manufactured by different materials (glass/epoxy, carbon/epoxy, Aluminium, and PVC). Considering loads and boundary condition, we study in static analysis the stress, strain and displacement, in dynamic analysis the modes shape and naturals frequencies, in fracture analysis the stress intensity factor, crack initiation and crack growth in order give the results by finite element method, then follow the evolution of the displacement, strain, stress SIF and first six naturals frequencies a function as crack propagation. As results we provide the best and idol materials versus the fatigue life of blade.
