Effect of boundaries parallel to crack on the SIFs of a semi-circular surface crack – A numerical study

This note is concerned with a surface semi-circular crack by using finite element method. Attention is specifically paid to the effect of the boundaries parallel to the crack on the stress intensity factors (SIFs). The numerical results illustrate that when the boundaries parallel to the crack are closer to the crack surface the effect of the boundaries parallel to the crack on the SIFs must be considered.
