摘要: 应用由Grady和Kipp推广的Mott公式,导出了物体破碎碎块的分形公式,求出了分形维数,然后将此公式和加载及加载时间联系起来,阐明了分形维数的物理本质。Abstract: By using the generalized Mott formula deduced by Grady and Kipp, the formulae describing the fragment distribution under dynamic loading and the fractal dimension are obtained and presented in this paper. Furthermore, their connection with the loading and loading time is established. On the basis of these connections, the physical meaning of the fractal dimension of the fragments distribution is better understood than before.
