Figure 12: The variation of axial stress according to the thickness for the three positions of the defect (with ratio of radius   ex in R / R constant and n kept constant=0.65).

Figure 13: Equivalent plastic strain distribution in FGM cylinder (n=0.65)

In Fig.12, the axial stresses are clearly affected by the presence and location of defects that amplify the level and distribution of stresses. The peaks of the stresses explain the compression in the form of elongation in a direction slightly
