An Effect of Shot Peening on Retardation and Growth of Short Fatigue Cracks in an Aircraft Al-alloy
Original language description
The paper contains the main results of an investigation of an effect of shot peening on residual fatigue life of specimens made of an aircraft V-95 Al-alloy containing physically short fatigue cracks. In the first part, an adaptation and verification ofdirect current potential drop method for detection and measurement of short crack growth is described and discussed. Physically short fatigue cracks were prepared under high cycle fatigue loading of the constant nominal stress amplitude +/- 160 MPa. Specimens with existing short fatigue cracks were shot peened using two different groups of parameters. Crack growth characteristics after shot peening were measured and compared with crack growth in specimens without shot peening. Retardation of crack growth was significant particularly for cracks shorter than 2 mm.
