Abstract
This paper describes the proposition of the characterizing method of fracture surface using the wavelet transformation, and the discussion of the validity of the method. The analyzed fracture surface is the fatigue fracture surface, and the method characterizes the local feature of striation. By the method, the boundary line between the striation area and the non-striation area is distinguished, and the striated surface ratio is calculated. The method estimates the absolute value of wavelet coefficient and the mother function is the Gabor function. Applying the method to the real fracture surface and the simulated fracture surface, the availability of the method is examined.
