摘要
提出了混凝土断裂能尺寸效应的分形描述方法.综合考虑试件尺寸和材料细观结构特征对断裂能的影响,使用分形理论建立了混凝土断裂能的分形尺寸效应模型;通过对实验数据的拟合表明该分形尺寸效应模型与多重分形尺寸效应律一样,能很好地与实验数据相吻合.
A fractal approach for the size effect on fracture energy of concrete was presented.Based on size effect analysis and mesoscopic structure character of material,a fractal size effect law（FSEL） of concrete fracture energy was proposed simultaneously.Comparison between the FSEL and the multi-fractal scaling law（MSFL） was done by using a serial experimental data.The analysis results show the FSEL is feasible and reliable.
