| 摘 要： | 不论是材料的断裂强度还是结构的承载能力均存在着明显的“尺度效应”．本文旨在较全面且系统地总结断裂力学中的相似方法、无量纲数及其断裂力学中有关的尺度率，并给出作者自己对某些问题的看法和认识 |
| 关 键 词： | 断裂 尺度效应 相似方法 量纲分析 自相 |

| Abstract: | The “scale effect” exists for either fracture strength of materials or carrying capabilities of structures.The aim of this paper is to summarize systematically the similarity method, dimensionless numbers and scaling laws in fracture mechanics, together with some author′s point of views. |
| Keywords: | fracture scale(or size)effect similarity method dimensional analysis self-similar anomalous dimension dimensionless number similarity parameter multiple fracture defects analogy turbulence vortices cascade |
