Figure 7. (a) The orthogonal KLMN has a central elliptic crack. (b): The crack fastly grows at the ends of big axis of ellipse and paralelly directs to compressive load σzz [29-38,40]. The elliptic crack vanishes and the propagation of crack in that area due to the union of invissible mesomicrocracks [39]
