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.
