| Abstract: | In this paper, we analyse theoretically the quantitative relationship of contrary change between K1c and DF based on the different structure of plastic domain near a crack tip and the different mechanism of fracture. It suggests that the analysis and the calculation of dissipation energy play an important role when fractal is applied to study dissipation system. |
