【摘要】 建立了材料断裂韧性与断裂表面分形维数的相关关系模型。结果表明，断裂韧性是分形维数、材料屈服强度、微结构尺寸及夹杂物体积分数等多参数的函数，并非只取决于分形维数更多还原

【Abstract】 This paper presented a correlative model of fracture toughness vs . fractal dimension of fracture surfaces. It is indicated that fracture toughness is a multivariate function of yield strength, microstructural length, fractal dimension of fracture and volume fraction of inclusions, instead of a monovariant function of fractal dimension of fracture.更多还原
