Abstract

Abstract In the present paper, the Fourier transform methof (FTM) was applied in a study of fatigue fracture surfaces of commercial aluminum in order to relate the geometrical parameters on the fracture surface to the microstructure of the material. The results indicate that the power spectrum and the wave number are inversely related. An exponent n was indexed by curve fitting the power spectrum peaks of the fracture profile and was shown to correlate with the crack propagation rate d a/d N, and d a/d N can be approximately from the correlation function.
