阐述了分形断裂的发展及应用，指出分形应用于材料的断口分析，可从实验方面和理论方面 得出分维D与材料特性、物理量的关系.总结了国内外氢致裂纹扩展的分形研究成果，表 明了分形断裂力学引入可为环境断裂研究提供新思路.
Developments and applications of fractal fracture a re illustrated,for the fracture analysis applied by fractal,fractal dimension and material properties and physical relationships are given by experiments or theory.Many progress made for the fractal of hydrogen-induced cracking are summ arized,and it showed that fractal fracture mechanics can supply a new method fo r environment fracture research.
