Heterogeneous Pattern Formation at Aluminum Surface — Fourier, Morphology and Fractal Analysis

Article Preview

Abstract:

Surface analysis of the aluminum thin plates plastically deformed under constrained cyclic deformation was performed by Fourier, morphology and fractal techniques. The plates are used for estimation of deformation damage and fracture in places with a priori known homogeneous and heterogeneous strain distribution. Advantages and disadvantages of Fourier, morphology and fractal techniques for characterization of the intersections and projections are discussed in the context of its applicability to investigation of plastic deformation and fracture (persistent strain planes and directions, strain localization angles and places, etc.).
