| Abstract: | Development of study on fractal theory and its application are briefly reviewed, and the measurement of fractal dimensions and its principle in mechanical behavior of solid materials are also reported in the paper. Further discussion on fractal micromechanisms of several typical advanced ceramics, involving monolithic structure, multiphase structure, multi composition hybrid compounding structure and bionics structure is presented in detail. The effective approach to achieve high toughness with the bionics structural and multi composition hybrid structural design is given together with a lot of suggestions and prospects for the application of fractals to the research of solid materials. |
