抄録

Characteristics of the free surface profile of aluminum sheets under uniaxial tension are examined by employing fractal analysis. As a fractal analysis method applicable to a self-affine surface, a zeroset method for generating intersections of the surface profile in a base plane is presented. It is found that the fractal dimension of a surface resulting from plastic deformation tends to be constant (2.35), and each asperity has a uniform fractal structure. Other fractal analysis methods, the box-counting method, power spectrum method and zeroset method were applied to surface profile curves obtained using a stylus profilometer, and the characteristics of various fractal dimensions are discussed. From these results, the geometry of surface profiles under uniaxial tension is clarified.
