Fig.5 Typical variation of accumulated strain with cycle number of the Ti-6Al-4V graded mesh (Insets schematically show the crack initiation and propagation in different constituents during cyclic deformation) (a) and X-ray tomography (XRT) of the graded meshes after being stopped at different stages of cycling shown in Fig.5a (b)[30] (dε1 / dN, dε2 / dN, and dε3 / dN are the cyclic ratcheting rates of graded mesh at different stages during cyclic deformation)
