摘要
本文,根据裂端塑性区的不同结构和不同的断裂机制,从理论上讨论了断裂韧性 K与断口分形维数D_F 间的定量关系。从而,指出了分形用于耗散系统研究时,耗散能的分析与计算将起着重要的作用。
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.
