| Abstract: | It is important to measure feasibility rock dynamic fracture toughness. From macrocrack-propagation, the influence of a/W on marble's dynamic fracture toughness is studied in this paper. Applied fractal theory in microstructure, we get satisfactory conclusion by quantitative analysis. 4figs., 1tab.,4refs. |
