Abstract : The main objective of current work is to investigate the how a crack propagates and grows in a typical Ti-6Al-4V material plate. By using the finite element method software (ANSYS13) were used to simulate crack growth and to compute the stresses and the stress-intensity factor. A specific plate design was selected and a corner crack was investigated, since engineers often detect this type of crack in plates. The VonMises stress near the crack tip is compared against the yield strength of the material. Under the tensile loading i.e in Mode-I the stress-intensity factor is compared against the materials fracture toughness. The results show that the plate can tolerate minute cracks in the structure. The fatigue strength of the structure is recommended to be assessed in the future.
