This research has investigated the influence of the chemistry of the materials, heat treatment and the methods and conditions of fracture on fractal dimendions of fractuered surfaces in order to express quantitatively the roughness of fractured surfaces with fractal dimensions. The results obtained are described in the following.<BR>1. The roughness of fractured surface can be expressed quantitatively with fractal dimensions.<BR>2. Fractal dimensions were influenced by the changes in grain sizes.<BR>3. The fractal dimension of fracture split connecting rod for a passenger car made in USA is relatively low and the surfaces of sample V with low dimension matched well.<BR>4. It is necessary to adopt much smaller span than 10μm of measurement to evaluate small rough surface like dimples on ductile fractured surface.
