3. Numerical results and discussion In Fig. 3, an example of the tangential stress distribution around the anchor’s corner at the radial distance of 4 mm directly obtained from the numerical simulations in ANSYS is presented.

q = -90°

Fig. 3. Tangential stress distribution at the radial distance of 4 mm around the anchor’s corner.

Fig. 3 shows the approximate angle q max where the tangential stress reaches its maximum, it is ca. 40° for the selected configuration ( t = 10 mm and R C = 4 mm). Note, that the q angle is measured counterclockwise with its zero value in the horizontal direction. Thus, the interval between -90° (lateral side of the anchor’s basement) and 180° (upper side of the anchor’s basement) was analysed. Fig. 4 represents the dependence of the maximum value of the tangential stress on the increasing radial distance considering various thicknesses of the anchor’s basement.
