Fig. 7. Angular distributions of the stress tensor components in the vicinity of the crack tip B generated with the theoretical solution (red line) and by finite element solution (black points). The theoretical solution is constructed with the help of truncated Williams series expansion: 1) the first row shows the four-term asymptotic solution; 2) the second row shows the six-term asymptotic solution; 3) the third row shows the eight-term asymptotic solution; 4) the fourth row shows the ten-term asymptotic solution5) the fifth row shows the twenty-term asymptotic solution.
