Sažetak
This paper provides some critical review of the history and state of art of methods taking account the T-stress values. The methods proposed in the literature which measure T stress at constant distance near the crack/or notch tip are not conservative. Example from CT specimen loaded in mode I obtained by using 2D finite element method with the software ANSYS 15.0, are taking to support this argument. Numerical results confirm that the Ts-tress is not constant near or on back to the crack/nocth tip. A numerical method based on the Volumetric Method developed by Pluvinage is used to defined the T-stress value to take into account. This method is characterized by the determination of the effective stress Tef over an effective distance Xef ahead of the crack tip.
