| 摘 要： | 分形几何(Fractal geometry)是近年来出现的一门应用数学分支。本文简要介绍了分形在材料断裂表面分析中的应用概况,并叙述了本文作者关于“延性断裂韧性与断裂表面的分形”研究工作。如果继续深入研究,将可从材料破坏的断口上直接分析并推知其断裂特性,从而为材料的失效分析提供一种简便而实用的新方法。

| Abstract: | Fractal geometry emerging in receat years is one of applied mathematics branches, This paper briefly introduced the application situation of fractals in analysis of fractured surfaces and narrated author's research work on "DUCTILE FRACTURE TOUGHNESS AND THE FRACTAL OF FRACTURED SURFACES". If the research proceed thoroughly we-will directly analyze the fractured surfaces of materials and deduce fracture characters, and so provide one of newer and practical methods for failure analysis of materials. |
