depends on the plastic properties of the material. At the end of the crack path close to the final fracture (point 7), despite the fact that an inclined curvilinear crack has already formed in the CTS specimen loaded by shear forces, a pseudo-mode-I scenario is realized at its tip. l=5  m Steel P2M Ti-6Al-4V Pure mode I
