III.2.1 Orientation of the micro-crack around the semi-infinite crack
The orientation of the microcrack around itself and around semi-infinite crack, gives the strain energy in each point of the material. By fixing the orientation of microcrack around itself and varying the orientation angle of microcrack around the semi-infinite crack, the following figures (figure 4(a,b) to 8(a,b)) present the strain energy values found around the semi-infinite crack.
