【摘要】 切缝尺寸对能否测得有效的岩石动态断裂韧度是一个关键的因素。本文从宏观上探讨了切缝尺寸对大理岩动态断裂韧度的影响 ,并用分形理论从微观上对其进行定量研究 ,获得了满意的结论。图 4,表 1 ,参 4。更多还原

【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.更多还原
