| Abstract: | After an analysis of the crack-source material of the cracked down skin of the right-middle-outer wing in an aircraft by means of the electron scanning microscope,a lot of features known as corrosion,stress corrosion and fatigue damage have been detected in the photomicrograph Thus the conclusion can be drawn that the crack mode of the cracked down skin is of corrosive fatigue cracking caused by stress corrosion |

| Keywords: | photomicrograph stress corrosion corrosion fatigue crack |
